........... In this equation,
"" is the sum of the geometric series, "" is the first term in the series, "" is the number of terms and "" is the ratio by which the terms increase
given:
+..
the ratio by which the terms increase is (if you multiply first term by you get second term ,if you multiply second term by you get , etc.)
so, , and ={ 1,2,3,.... }
