Question

Find the wrong number in the following number series:
10, 17, 26, 36, 50

A.

26

B.

36

C.

50

D.

17

Correct option is B

Given Series: 10, 17, 26, 36, 50
Step-by-Step Logic:
17 - 10 = 7 (odd)
26 - 17 = 9 (odd)
36 - 26 = 10 (even, which is incorrect)
50 - 36 = 14 (even, which is incorrect)
According to the pattern, the differences should be increasing odd numbers like 7, 9, 11, 13, etc.
7 (odd)
9 (odd)
11 (should be next, not 10)
13 (should be next, not 14)
Thus, 36 is the wrong term in the series. It should be 35 to follow the correct pattern.
Final Correct Option: (B) 36
