Question

Select the number that will come next in the following series

3, 28, 117, 336, ?
1. 356
2. 775
3. 765
4. 3275

Answer 1

Correct Answer - Option 2 : 775

The pattern followed here is

(1² + 1³ + 1⁴) = 3

(2² + 2³ + 2⁴) = 28

(3² + 3³ + 3⁴) = 117

(4² + 4³+ 4⁴) = 336

So, the next number in the series will be

(5² + 5³ + 5⁴) = 775

Hence, the next term in the series is 775.
