Using the formula for the sum of an arithmetic sequence, what is the sum of the first 30 terms?
The formula for the Sum of Terms in an Arithmetic Sequence is:
highlight%28S%5Bn%5D=%28n%2F2%29%282a%2B%28n-1%29d%29%29
where Sn=sum of the n terms
a=the first term
n=number of terms
d=common difference
All you've given me is n=30, I need a and d to give you an actual answer.
Happy Calculating!!!!
