Complete the following sequence: 5, 72, 412, 2658, __________?
Explanation:
The series is in the form of 2nan + 62 (n − 1), n > 1, where a1 = 5
For n = 2, a2 = 5 × 2 + 62 × 1 = 72 For n = 3, a3 = 72 × 4 + 62 × 2 = 412 For n = 4, a4 = 412 × 6 + 62 × 3 = 2658 For n = 5, a5 = 2658 × 8 + 62 × 4 = 21512
Thus the correct option is C.
