    D.

    Step-by-step explanation:

    r = 3

    a1 = 2

    Our explicit formula is an = a1 (r) ^ (n-1)

    Simply plug in the terms

    an = 2 (3) ^ (n-1)

    D. aₙ = 2*3ⁿ⁻¹

    Step-by-step explanation:

    It is GP with common ratio of 3 as 6/2=18/6=54/18=162/54 = 3 and the first term of 2

    then aₙ = 2*3ⁿ⁻¹ is the formula

    Option D is correct one
