Question

the explicit formula for a particular sequence is f (n)= 3+5 (n-1) using the explicit formula, find the 17th term

Answer 1

An=a1+d(n-1)
a1=first term
d common differnce
n=which term

jsut sub 17 for n
f(17)=3+5(17-1)
f(17)=3+5(16)
f(17)=3+80
f(17)=83

answer is 83

Answer 2

F(n)=3+5(n-1)

17 th term is when n=17, therefore:
f(17)=3+5(17-1)
f(17)=3+5(16)
f(17)=3+80
f(17)=83

Answer: the 17th term is 83
