Question

Given the explicit expression f(n)=2n+10, write a set showing the sequence, and write a recursive expression.

A. {12, 14, 16, 18,...}, f(1)=12 and f(n)=f(n−1)+2 for n>1*************************
B.12, 14, 16, 18,...}, f(1)=12 and f(n)=f(n−1)+4 for n>1
C.{2, 4, 6, 8,...}, f(1)=2 and f(n)=f(n−1)+2 for n>1
D.2, 4, 6, 8,...}, f(1)=2 and f(n)=f(n−1)+4 for n>1

Answer 1

Answer: your answer is A.

Step-by-step explanation: The next possible answer could have been C.{2, 4, 6, 8,...}, f(1)=2 and f(n)=f(n−1)+2 for n>1 but the recursive formula has to be divided in to 12 equal sections and one does not allow that. An EXPONATAIL sequence could represent some of the term, but since the variable is irreplaceable....You can tell be looking at 12, 14, 16, 18,...}, f(1)=12 and f(n)=f(n−1)+2 for n>1 could represent the term....

In other words your answer WAS correct!!!
