Identify the number that does NOT belong to the following series.
34, 63, 94, 131, 172, 225
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 225.
The series follows this pattern:
34 + 29 = 63, 63 + 31 = 94, 94 + 37 = 131, 131 + 41 = 172, 172 + 43 = 215
The difference is followed by consecutive prime number series. As 215 will come in place of 225 so option 4 is the correct answer.
Hence, the correct answer is option 4.
