Question

What will come in place of question mark (?) in the following number series?

28, 36, 63, 127, 252, ?

1. 468
2. 568
3. 478
4. 216
5. None of these

Answer 1

Correct Answer - Option 1 : 468

Considering the above series,

28, 36, 63, 127, 252, ?

The logic of the series can be explained as,

36 – 28 = 8 = 2³

63 – 36 = 27 = 3³

127 – 63 = 64 = 4³

252 – 127 = 125 = 5³

By observing the pattern,

? – 252 = 6³ = 216

⇒ ? = 468

∴ The value of ? is 468
