Question

What is the sum of the infinite geometric series?

Answer 1

The answer is going to be D -6

r=1/2

Sn=a(1-r^n)/1-r

S(infinite sign) = a/1-r

S(infinite sign) = -3/1-1/2

S(infinite sign) = -3/1/2

S(infinite sign) = -3/1/1*2/2-1/2

S(infinite sign) = -3/1*2/2-1/2

S(infinite sign) = -3(3*2)

S(infinite sign) = -1*6

S(infinite sign) = -6

Answer 2

The answer to gonna be A -93/16
