Hi, given the property for a series such that the second term is got by adding a constant 'd' to the 1st term and the 3rd term is got by multiplying the 2nd term by another constant 'r' and so on ..how can we arrive at a generalised formula for nth term of the series if we are given the 1st term , d and r?
E.g if first term = 2, d = 2 ,r = 3 then the series is :
2,4,12,14,42,44,132,134,...
so the 4th term is 14, 7th term is 132 and so on..
Thanks
