Abstract: Abstract The student is probably already familiar with the result that the sum of the infinite geometric progression: 1 + x + x 2 + x 3 + ... + x r + ... is equal to 1/(1 — x), as long as the common ratio x is numerically less than 1. We may thus write: 1 1 − x = 1 + x + x 2 + x 3 + ... + x r + ... ( | x | < 1 ) $$ \frac{1}{{1 - x}} = 1 + x + {x^2} + {x^3} + ... + {x^r} + ...\left( {\left| x \right|
