Q:
# What is the third term of the sequence defined by the recursive rule f(1)=3 f(n)=f(n-1)+4

Accepted Solution

A:

What is the third term of the sequence defined by the recursive rule f(1)=3 f(n)=f(n-1)+4

Need f(2):

f(2)=f(2-1)+4

f(2)=f(1)+4

f(2)=(3)+4=7

FIND f(3):

f(3)=f(3-1)+4

f(3)=f(2)+4

f(3)=(7)+4

f(3)=11

Need f(2):

f(2)=f(2-1)+4

f(2)=f(1)+4

f(2)=(3)+4=7

FIND f(3):

f(3)=f(3-1)+4

f(3)=f(2)+4

f(3)=(7)+4

f(3)=11
