Which of the following will not be a number in the following series?
64, 125, 216, 343, 512, ......
Show answer & explanation
Correct answer: D
Explanation
Given:
Series = 64, 125, 216, 343, 512
64 = 4³
125 = 5³
216 = 6³
343 = 7³
512 = 8³
9³ = 729
10³ = 1000
11³ = 1331
12³ = 1728
1000, 1331, 1728 → all perfect cubes
829 → not a perfect cube
