Triangle Ratio Generator

written by Colin Joye 5/00
This program generates the (x+1)th ratio of the triangle series by taking the (x+1)th number and dividing it by the (x+2)th. The series follows the construction of a triangle: 0, 1, 3, 6, 10, 15.... A 10-pin bowling pin formation occurs at x=4. Enter the number for the (x+1)th ratio below as a positive integer value. The ratio between adjacent elements approaches 1.
  x+1:     

ratio:     
difference:             
(x+1)th:          
(x+2)th:
