The formula of the partial sum of the first n terms of a geometric series is:


Sn=(a1(1-r^n))/(1-r)

In this case, a1 is 6 (the first term of the series) and r is 1/4 (the base). By replacing 16 for n and the rest of the values we should get:


Sn=(6(1-((1)/(4))^(16)))/(1-((1)/(4)))\approx8

Then, the sum of the given geometric series is 8
