Lesson Steps

Step	Type	Explanation	Answer
1	Problem	Identify the missing numbers 22,29, _ ,43, _ , _.
2	Step	To identify the missing numbers in the sequence 22, 29, _, 43, _, _, let’s try to find the pattern:
3	Step	The first number is	22
4	Step	The second number is 29, which is obtained by adding 7 to the first number	22 + 7 = 29
5	Step	The third number is missing, and it should be obtained by adding 7 to the second number	29 + 7 = 36
6	Step	The fourth number is 43, which we already have in the sequence.
7	Step	The fifth number is missing, and it should be obtained by adding 7 to the fourth number	43 + 7 = 50
8	Step	The sixth number is missing, and it should be obtained by adding 7 to the fifth number	50 + 7 = 57
9	Step	So, the missing numbers are 36, 50, and 57, and the complete sequence is 22, 29, 36, 43, 50, 57.
10	Sumup	Can you summarize what you’ve understood in the above steps?
11	Choice.A	Differences: 62 - 47 = 15, 71 - 62 = 9 Incorrect, as the differences are not consistent with the given pattern	47,62,71
12	Choice.B	Differences: 63 - 46 = 17, 71 - 63 = 8 Incorrect, as the differences are not consistent with the given pattern	46,63,71
13	Choice.C	Differences: 50 - 36 = 14, 57 - 50 = 7 Correct! The differences are consistent with the given pattern	36,50,57
14	Choice.D	Differences: 63 - 47 = 16, 70 - 63 = 7 Incorrect, as the differences are not consistent with the given pattern	47,63,70

Problem

Identify the missing numbers 22,29, _ ,43, _ , _.

Step

To identify the missing numbers in the sequence 22, 29, _, 43, _, _, let’s try to find the pattern:

Step

The first number is

Step

The second number is 29, which is obtained by adding 7 to the first number

22 + 7 = 29

Step

The third number is missing, and it should be obtained by adding 7 to the second number

29 + 7 = 36

Step

The fourth number is 43, which we already have in the sequence.

Step

The fifth number is missing, and it should be obtained by adding 7 to the fourth number

43 + 7 = 50

Step

The sixth number is missing, and it should be obtained by adding 7 to the fifth number

50 + 7 = 57

Step

So, the missing numbers are 36, 50, and 57, and the complete sequence is 22, 29, 36, 43, 50, 57.

Sumup

Choice.A

Differences: 62 - 47 = 15, 71 - 62 = 9 Incorrect, as the differences are not consistent with the given pattern

47,62,71

Choice.B

Differences: 63 - 46 = 17, 71 - 63 = 8 Incorrect, as the differences are not consistent with the given pattern

46,63,71

Choice.C

Differences: 50 - 36 = 14, 57 - 50 = 7 Correct! The differences are consistent with the given pattern

36,50,57

Choice.D

Differences: 63 - 47 = 16, 70 - 63 = 7 Incorrect, as the differences are not consistent with the given pattern

47,63,70
