Find the 15th term in the geometric sequence shown below.

1, 3, 9 ...

Answer:'3^14

Step-by-step explanation:

This geometric sequence has common ratio 3 and first term 1.

Thus, the general formula for the nth term is a (n) = 1*3 (n - 1).

The 15th term is thus a (15) = 1*3^ (n - 1) = 3^14.

Step-by-step explanation:

a₁ = 1

r = 3/1 = 3

an = a₁rⁿ⁻¹

a₁₅ = 1 * (3) ¹⁴

a₁₅ = 4782969
