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?
Please no.further a little
Please could I get the complete solution
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
