Question

Given the functions f(n) = 25 and g(n) = 3(n – 1), combine them to create an arithmetic sequence, an, and solve for the 12th term

Answer 1

an = 25 – 3(n – 1); a_12 = –11
an = 25 – 3(n – 1); a_12 = –8
an = 25 + 3(n – 1); a_12 = 58
an = 25 + 3(n – 1); a_12 = 61

Answer 2

nvm i got it right thanks :)
