Question

In the series
s', 10, 20, 40
what will be the l0
term?​

Answer 1

Step-by-step explanation:

Answer. Its like 5 * 2 = 10, 10 * 2 = 20, 20 * 2 = 40,... So, the series is a G.P. in which a = 5 and r = 2. Let the number of terms be n.

Answer 2

Step-by-step explanation:

Gp with Common ratio 'r' = 2

so 10th term = a*r(n-1)

here n = 10 and a= 10(first term)

hence 10th term will be 5120

Hope this helps :^)
