a + ar^4 = 34
ar * ar^2 * ar^4 = 512
a(1+r^4) = 34
a^3 r^7 = 512
Looks kind of messy, but since the only factors of 34 are 2 and 17, it appears that
a=2 and r=2
I think the second condition should have used the 4th term, rather than the 5th. If so, then since 2^9=512, that fits with what we have so far.
in a GP the sum of first and fifth term is 34 and the product of second ,third and fifth term is 512.find the numbers.
