Answer 1

Hay sir,

According to the question we know that a = 2

and r = 2 , n = 10


Now, we can use this formula for solving

$s _{n} = \frac{a(r {}^{n } - 1)}{r - 1}$

$s _{10} = \frac{2(2 {}^{10} - 1) }{2 - 1}$


$= 2(1024 - 1)$


$2 \times 1023$


$2046$



I hope it's help you

r = 2
n = 10

S10 = 2(2^10-1)/2-1 = 2(1024-1) = 2046
