    an = 11 - 2(n - 1); a31 = -49 an = 11 - 2(n - 1); a31 = -51 an = 11 + 2(n - 1); a31 = 71 an = 11 + 2(n - 1); a31 = 73

    when we combine these functions we get 11 -2(n-1) ..... eq#1 now to find a31 put n=31 into eq#1 11-2(31-1) 11-2(30) 11-60 -49 is correct answer So 1 is correct answer

    \[a_n=f(n)+g(n)\]\[a_n=11-2(n-1)\]\[a_{31}=11-2(31-1)\]
