Question

Find 8tn and 10tn term of a gp whose first term and common ratio are 6 and 2 respectively

Answer 1

Answer:

8th term = 768

10th term = 3072

Step-by-step explanation:

let a be the first term and r be the common ratio

a = 6

r = 2

nth term = ar^n-1

8th term = 6*2^8-1

               =6*2^7

               =6*128

               =768

10th term = 6*2^10-1

                =6*2^9

                =6*512

                = 3072
