Question

The fifth term of an exponential sequence is greater than the fourth term by 27/2 and the fourth term is greater than the third term by 9. Find the first term and the common ratio

Answer 1

You have several equations to work with.
We know tn=a(r)^n-1
and that
t5 = t4 + 27/2
and that
t3 = t2 - 9
we also know things like t5=ar^4
Does this inspire you to use the equations and use some of your solving methods?

Answer 2

Please no.further a little

Answer 3

Please could I get the complete solution

Answer 4

The fifth term of aG.P is greater than the fourth term by 13.5,and the fourth term is greater than the third by 9.find : the common ratio and common difference
