Question

Complete the series given below by choose the missing term out of the given alternatives.
6, 7, 15, 46, 185, ?

• A. 226
• B. 230
• C. 271
• D. 926

Answer 1

Answer: (D)

926

Preceding term is multiplied by 1, 2, 3, 4, 5 respectively and then 1 is added to the product.

6 $\times$ 1 + 1 = 7

7 $\times$2 + 1 = 15

15 $\times$ 3 + 1 = 46

46 $\times$ 4 + 1 = 185

So, next term will be:

185$\times$5 + 1 = 926 (option D)
