Question 2551 | Mathematics Past Questions

To find sum to infinity, \(a\) and \(r\) are required:

\(ar = -\frac{1}{2}\)...(1)

\(ar^2 = \frac{1}{4}\)...(2)

Divide equ 2 by 1:

\(\cfrac{ar^2}{ar} = \cfrac{\frac{1}{4}}{-\frac{1}{2}}\)

\(r = -\frac{1}{2}\)

Then input the value of \(r\) in one of the equ \(a = 1\):

This gives us: \(\frac{1}{1-\frac{1}{2}} = \frac{2}{3}\)
