Question

0, 2, 8, 26, 80, 242, 728, 2168, 6560, 19682
write a recursive formula or explicit formula?

Answer 1

Hint: each of them increase by \[2 \times 3^{(n-1)}\]

Answer 2

2168 should be 2186

Answer 3

Thus the recursive formula will be\[A_{1}=0...and...A_{n}= 3A_{n-1}+2\]

Answer 4

A_n = [3 ^ (n-1)] - 1 for 1 <= n < = 10
