Question

What is the 5th term of the sequence defined by an = a1 + 6(n -1), when a1 = 2?

A. 6
B. 32
C. 26
D. 23

Answer 1

an = a1 + 6(n -1), when a1 = 2?
a(5) = a1 + 6(n -1)= 2 + 6(4) = 26

answer is


C. 26

Answer 2

a(n)=a+6(n-1)

a(n)=a+6n-6  and a=2

a(n)=2+6n-6

a(n)=6n-4

a(5)=6(5)-4

a(5)=30-4

a(5)=26
