Question

Will Fan and Medal, 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

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.

an = 25 − 3(n − 1); a12 = −11
an = 25 − 3(n − 1); a12 = −8
an = 25 + 3(n − 1); a12 = 58
an = 25 + 3(n − 1); a12 = 61

Answer 2

I dont understand how to combine them exactly.
