Find the sum to infinity to the following series 3 + 2 + \(\frac{4}{3}\) + \(\frac{8}{9}\) + \(\frac{16}{17}\) + .....
A
1270
B
190
C
18
D
9
correct option: d
3 + 2 + (\frac{4}{3}) + (\frac{8}{9}) + (\frac{16}{17}) + .....
a = 3
r = (\frac{2}{3})
s (\alpha) = (\frac{a}{1 - r}) = (\frac{3}{1 - \frac{2}{3}})
= (\frac{3}{\frac{1}{3}})
= 3 x 3
= 9
