Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 64.
Given series: 2, 9, 28, 64, 126, 217, 344, 513
The logic used here is:
13 + 1 = 2
23 + 1 = 9
33 + 1 = 28
43 + 1 = 65
53 + 1 = 126
63 + 1 = 217
73 + 1 = 343
83 + 1 = 513
The number that does not belong to the series is 64.
Hence, the correct answer is 64.
