Basic Formula Evaluation.
Let us take an instance of a sequence {ai}={ai, a2, a3,……}; to find the sum of these digits, we
often add all or some of these digits. We always write all the letters that is.
a1 + a2 + a3 + · · · + ai + · · · . To avoid this, we use the sigma notation, Σ, to
represent the sum of all these terms:

Let us Consider an example to depict the above:
This points that ai = i, and we will with i = 1, so a1 = 1,
