So it should be 200*(1r)^4 = 170sorry q5
You just need to know what a geometric sequence is.oh so is it just substitution?
yeah so tn=t1xr^n1 and just sub into the formula?You just need to know what geometric series is
I would avoid x and replace that with * but yes. the nth term of geometric sequence is a*r^(n1)yeah so tn=t1xr^n1 and just sub into the formula?
