No, that can't be right.
Since every term is reduced by 8 from the previous term, and you start out with an integer, the sum must be an integer. The sum will also be negative in this case. There will be more negative terms than positive terms in the first 19.
What is the sum of the first 19 terms of the series: 63 + 55 + 47 + 39 + 31 + …?
I think it is 769.5
is it right?
