### Description

If f(1) = 3 and f(n) = -2f(n-1) + 1 then f(5) will equal what

## Explanation & Answer

Thank you for the opportunity to help you with your question!

From f(n) = -2f(n-1) + 1 you get that f(2)=-2f(1) + 1=-2*3+1=-5

f(3)=-2f(2) + 1=-2*(-5)+1=11

f(4)=-2f(3) + 1=-2*11+1=-21

And Finally f(5)=-2f(4) + 1=-2*(-21)+1=43

f(5)=43
