Ok, from your information . To get just substitute for . Thus .
Now divide the two. Can you see the simplification?
okay the question is as follows:
write the first three terms of tn= 5(2)^ n-1. what is the value of
okay so the first three terms are as follows:
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!
