Step-by-step explanation:
so the infinite series is
a + ar + ar^2 + ar^3....
= a(1 + r + r^2 + r^3...)
= a(1 + r(1 + r + r^2 + r^3...))
ignore the a for a second
imagine it's 1
we call this sum S
S = 1 + r(1 + r + r^2 + r^3...)
S = 1 + rS
S - rS = 1
S(1 - r) = 1
S = 1/(1-r)
and the difference for that series is every term is multiplied by a
or S = a/(1-r)
