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)

The two kinds of sums typically refer to the arithmetic sum and the geometric sum. An arithmetic sum is the total of a sequence of numbers where each term increases by a constant difference, while a geometric sum involves a sequence where each term is multiplied by a constant ratio. Both types of sums can be expressed using specific formulas to calculate their totals efficiently.
It is an arithmetic sequence for which the index goes on and on (and on).
An arithmetic sequence is a list of numbers which follow a rule. A series is the sum of a sequence of numbers.

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.
That refers to the sum of an arithmetic series.
