It is just as possible to imagine the number 10+1.Such a sequence is said to be infinite: it is unlimited.
It is meaningless to ask for the sum of integers in the number system. It would be equally meaningless to ask for the sum of the numbers in any other infinite arithmetic progression(A.P.) if it was an increasing A.P. or decreasing A.P. A G.P. may also be infinite.
Consider the infinite G.P. 1,1/2,1/4,… You could continue writing the terms of this G.P . indefinitely. If you did so, the number of terms would increase without limit. This fact is shown in symbol form thus: n--infinity, the arrow meaning approaches, and & being the symbol for infinity. The statement is read “n approaches infinity” or “ tends to infinity” As n --infinity, what happens to the sum of the G.P.? To answer this question, notice first that the number of terms increases, the value of the n-th term bห้อยn gets smaller and smaller. It approaches zero; that is, bห้อยn-- 0.
If you add successive terms, you will add a smaller quantity each time.
