Question

Find the next element that replace the ? Logically

7, 24, 58, 126, ?

The correct answer is

262

Study the differences between consecutive terms of 7, 24, 58, 126.

24 - 7 = 17; 58 - 24 = 34; 126 - 58 = 68.

The differences 17, 34, 68 keep doubling, so the next difference is 68 x 2 = 136.

Therefore the next term is 126 + 136 = 262.

Hence the missing element is 262.
