You have several equations to work with.
We know tn=a(r)^n-1
t5 = t4 + 27/2
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?
3,5,-5... The first term in the sequence of #'s shown above is 3. Each even # term is 2 more than the previous term and each odd # term, after the first, is -1 times the previous term. For example, the second term is 3+2, and the
