    PLEASE MARK ME AS BRANLIEST!!!!!

    Step-by-step explanation:

    a1 = first term; an= an-1 + d a1 = the first term in the sequence an = the nth term in the sequence an-1 = the term before the nth term n = the term number d = the common difference.

    {10, 15, 20, 25, 30, 35, } first term = 10, common difference = 5 recursive formula: a1= 10; an= an-1 + 5

  • f(n) = f(n-1) + 12

    f(1) = 7

    f(2) = (7-1) + 12 = 18

    f(3) = (18-1) + 12 = 29

    f(4) = (29-1) + 12 = 40

    f(5) = (40-1) + 12 = 51

    7, 18, 29, 40, 51
