    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
