5660

6560

6750

6630

Correct Answer : Option (D) - 6630

Explanation :

Let first no. be "k" and multiple be "l"...start value of y with 3 then,

[(k x y) + {l x (l-1)}]

Thus, we get

15 x 3 + 3 x 2 = 51

51 x 4 + 4 x 3 = 216

216 x 5 + 5 x 4 = 1100

1100 x 6 + 6 x 5 = 6630

6630 x 7 + 7 x 6 = 46452

Therefore, the missing number is 6630.
