okay the question is as follows:

write the first three terms of tn= 5(2)^ n-1. what is the value of

tn/tn-3?

okay so the first three terms are as follows:

t1= 5(2)^1-1=5X1=5

t2= 5(2)^2-1=5X 2=10

t3= 5(2)^3-1=5X4= 20

okay I am a little bit confused about the next part: what is the value of

tn/tn-3? how would I do this? thanks for your help!
