0:03 hi kids here we have another lesson
0:06 Explorer another set of activities to
0:09 solve another learning to unlock I'm
0:24 in this video you will learn how to
0:27 determine the missing term or terms in a
0:28 sequence of numbers
0:31 a number sentence is a list of numbers
0:34 arranged in a row we call each number in
0:37 a sequence a term
0:39 try a look at a sequence of numbers in
0:40 the Box
0:44 can you identify the missing terms
0:47 there are several steps in order to find
0:50 the meeting term or terms in a number sequence
0:52 sequence
0:54 all we have to do is to follow these
0:58 Three Steps step one the pattern
1:00 Step 2 test
1:03 step 3 better me
1:07 for step one look for the pattern
1:11 in the given number sequence 5 10 blank
1:15 20 and blank each term is formed by
1:17 adding 5 to the preceding number
1:19 so the pattern of the given number
1:23 sequence is plus five always remember
1:26 that if the sequence is increasing the
1:28 operation of the pattern is either
1:31 addition or multiplication
1:34 but if the sequence is decreasing the
1:38 operation is subtraction or division
1:42 for Step 2 test the pattern make sure to
1:43 check the pattern if it is correct to
1:47 the whole sequence from 5 to 25. if you
1:51 are going to add 5 to 10 we will find 15
1:53 as the first missing term in a sequence
1:58 10 plus 5 equals 15. by following the
2:02 same procedure with 20 added by 5 20
2:04 plus 5 we will then find the last
2:10 missing term as 25 20 plus 5 equals 25.
2:13 and for the last step
2:15 you are going to determine and write the
2:18 missing term or terms after checking if
2:20 the battery is true up to the last term
2:22 you can now determine the missing term
2:26 or terms so the missing terms are 15 and 25.
2:28 25.
2:31 to know further more about the lesson
2:34 let's have these activities find the
2:36 missing term or terms in the given
2:43 to determine the missing term or terms
2:45 in the given number sequences we will
2:47 follow the steps we learned in this lesson
2:48 lesson
2:51 in the first number sequence the given
2:53 terms are inside two different shapes
2:56 which are star and hearts for step one
2:58 we should look for the pattern since the
3:01 given terms are inside different shapes
3:04 let us first look closely at the numbers
3:06 inside the Stars the numbers inside the
3:09 stars are in increasing order
3:11 the mathematical operation would be
3:14 either addition or multiplication
3:17 as we can see the terms are added by
3:23 even numbers 2 4 and 6 consecutively
3:26 now let us take a closer look at the
3:28 numbers in the hearts the numbers inside
3:31 the hearts are also in increasing order
3:34 therefore the mathematical operation
3:37 will be either addition or
3:40 multiplication as well in this number
3:43 sequence the terms are added by odd
3:47 numbers 3 5 and 7 consecutively
3:50 After figuring out the patterns let us
3:53 now proceed to step 2. we should test
3:55 the pattern make sure to check the
3:57 pattern if it is true or correct to the
3:59 whole number sequence
4:01 let's proceed to step three
4:03 let's determine and write the missing
4:06 terms after checking if the pattern is
4:09 true after the last number you can now
4:11 determine and write the missing term or
4:14 terms the two missing terms are 8 and 20.
4:16 20.
4:18 now let us find the missing terms in the
4:27 step one look for the pattern as we can
4:30 see the terms are in decreasing order so
4:32 the mathematical operation of the
4:35 pattern is either subtraction or division
4:36 division
4:39 after a closer look to the numbers we
4:44 can see that if we divide 352 by 2 the
4:47 quotient is 176.
4:51 as well as 44 if divided by 2 we will
4:55 get 22 as quotient therefore we came up
4:58 to a pattern of dividing the terms by
5:00 two After figuring out the patterns let
5:03 us now proceed to step two Let's test
5:06 the pattern make sure to check the
5:08 pattern if it is true or correct in the
5:10 whole number sequence let's proceed to
5:13 the last step let's determine and write
5:15 the missing terms so the missing terms
5:22 these are the key Concepts that you need
5:24 to remember
5:27 sequence is a list of numbers arranged
5:29 in a row
5:32 a term is what we call each number in a sequence
5:33 sequence
5:36 and to find the missing terms or terms
5:39 in a sequence remember these three steps
5:42 the pattern the test and the determine
5:45 let's try this activity
5:48 find the missing term or terms in the
6:03 determine the missing term or terms in
