the best way to do this is to use a calculator wolfram alpha is the best one for the job type in "interpolate((1915,4.156),(1922, 4.857),(1946, 7.16),(1991, 29.989))" without quotes to get the following http://www.wolframalpha.com/input/?i=interpolate%28%281915%2C4.156%29%2C%281922%2C+4.857%29%2C%281946%2C+7.16%29%2C%281991%2C+29.989%29%29
