what is the sum of the finite arithmetic series 26+29+32
The sum of a finite arithmetic series can be found using the formula:
Sn = n/2 * (a1 + an),
where Sn is the sum of the series, n is the number of terms, a1 is the first term, and an is the last term.
In this case, the first term (a1) is 26, the last term (an) is 32, and there are 3 terms in total (n = 3).
So, the sum Sn is:
Sn = 3/2 * (26 + 32)
Sn = 3/2 * 58
Sn = 87
Therefore, the sum of the finite arithmetic series 26 + 29 + 32 is 87.
