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.
To find the sum of the first 28 terms of an arithmetic sequence, you need the first term (a) and the common difference (d). The formula for the sum of the first n terms (S_n) of an arithmetic sequence is S_n = n/2 * (2a + (n - 1)d). Once you have the values of a and d, plug them into the formula along with n = 28 to calculate the sum.
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.

An arithmetic sequence is a list of numbers which follow a rule. A series is the sum of a sequence of numbers.
