Question

Which Term Of the following Sequences root 3,3,3root3,.....is 729

Answer 1

Given a = root 3, n = 729, r = root 3


We know that tn =  a.r^n-1

                 = (root 3) * (root 3)^n-1 = 729

                 = (root 3) * (root 3)^n-1 = 3^6

                 = (root 3)^n = (root 3)^12

                  n = 12


Hope this helps!
