It is hilarious how much everyone is struggling with this.

you can also write a loop looking something like this:

declare (often dim) i, answer as integer

answer=0

for i=1 to 40
answer = 8+2i + answer
next i

return answer

answer = the sum of all the seats

Honestly.

Sn = n(a1 + an) / 2
= 40(10 + 88) / 2
= 1960

40*10+40*([0+78]/2)=1960

Just put it in excel, drag the column down to how many rows there are, sum it up. Who needs math.

Because you're forgetting to include the first row in your sum...
