Which number from 7, 10, 16, 26, 37, 52 does not belong to the group?
Show answer & explanation
Correct answer: D
Explanation
1st term = 7
2nd term = 7 + 3 = 10
3rd term = 10 + 6 = 16
4th term = 16 + 9 = 25
5th term = 25 + 12 = 37
6th term = 37 + 15 = 52
Hence the series:
7, 10, 16, 25, 37, 52
Correct answer: 26
