A geometric sequence is a sequence, such that each term is given by a multiple of q of the previous one. A geometric series consists out of the sum of all former values of a geometric sequence..
GeomSn(a1, q, n)
the sum as numeric value
the first element of the sequence
the factor of the sequence
number of elements to include in the sum

sum
GeomSn(a1=3, q=2, n=5) # calculates the sum of the first 5 elements of the sequence (gseq <- 3 * (2^(0:5))) sum(gseq) GeomSn(a1=3, q=2, n=0:5)
