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.
a1=2 d=3 an=a1+(n-1)d i.e. 2,5,8,11,14,17....

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.
That refers to the sum of an arithmetic series.
The sum of the first 12 terms of an arithmetic sequence is: sum = (n/2)(2a + (n - 1)d) = (12/2)(2a + (12 - 1)d) = 6(2a + 11d) = 12a + 66d where a is the first term and d is the common difference.
