What is the sum of the first 19 terms of the arithmetic series?
Did my answer ever send?
Correct me if I am wrong, lol. But is it
It wasn't correct, but I had already put my answer in and it was right. Thank you so much for the effort though.
Im sorry! I am curious though, what was the answer??
Don't you know the formula for Arithmetic Series?
S = N/2 [2F + (N - 1)*D], where N=Mumber of terms, F=First term, D =Common difference
S = 19/2 [2*3 + (19 - 1)*5]
S = 9.5 [6 + (18*5) ]
S = 9.5 [6 + 90 ]
S = 9.5 x 96
S = 912
