In series 1, only one number is wrong. If the wrong number is corrected, the series gets established following a certain logic. Complete series 2 with same logic and answer the given question.
| Series 1: | 5 | 9 | 25 | 91 | 414 | 2282.5 |
| Series 2: | 3 | a | b | c | d | e |
What will come in place of (c) ?
Explanation
Given number series 1 follows the logic
⇒ 5×1.5+1.5= 7.5+1.5= 9
⇒ 9×2.5+2.5= 22.5+2.5= 25
⇒ 25×3.5+3.5= 87.5+3.5= 91
⇒ 91×4.5+4.5= 409.5+4.5= 414
⇒ 414×5.5+5.5= 2277+5.5= 2282.5
Similarly, series 2
(a)⇒ 3×1.5+1.5= 4.5+1.5= 6
(b)⇒ 6×2.5+2.5= 15+2.5= 17.5
(c)⇒ 17.5×3.5+3.5= 6125+3.5= 64.75
Hence, Option D is correct.
