Given an arithmetic sequence whose first term is a, last term is l and common difference is d is:
The series of partial sums, Sn, is given by
Sn = 1/2*n*(a + l) = 1/2*n*[2a + (n-1)*d]
an arithmetic sequeunce does not have the sum to infinty, and a geometric sequence has.
an = a1 + d(n - 1)

It is an arithmetic sequence for which the index goes on and on (and on).
The formula for the sum of an arithmetic sequence is ((first number) + (last number)) x (how many numbers) / 2, in this case, (1 + 100) x 100 / 2.The formula for the sum of an arithmetic sequence is ((first number) + (last number)) x (how many numbers) / 2, in this case, (1 + 100) x 100 / 2.The formula for the sum of an arithmetic sequence is ((first number) + (last number)) x (how many numbers) / 2, in this case, (1 + 100) x 100 / 2.The formula for the sum of an arithmetic sequence is ((first number) + (last number)) x (how many numbers) / 2, in this case, (1 + 100) x 100 / 2.
An arithmetic sequence is a list of numbers which follow a rule. A series is the sum of a sequence of numbers.
an arithmetic sequeunce does not have the sum to infinty, and a geometric sequence has.

That refers to the sum of an arithmetic series.
