Question

PART A Write the explicit formula in function form. an= -3+5 (n-1) F(n)= PART B what is the Y intercept of the function? (______,______)

Answer 1

Given data:

The given expression is an=-3+5(n-1).

The given expression can be written as,

$\begin{gathered} a_n=-3+5(n-1) \\ =-3+5n-5 \\ =-8+5n \end{gathered}$

Thus, the explicit formula for the function is F(n)=-8+5n.
