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

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
