To find the sum of this arithmetic series, we can use the formula for the sum of an arithmetic series:
Sn = (n/2)(first term + last term)
In this case, the first term is 1, the last term is 30, and there are 30 terms.
Sn = (30/2)(1 + 30)
Sn = 15(31)
Sn = 465
The sum of the series 1+2+3...+29+30 is 465.
Find the sum: 1+2+3…+29+30.
