The last number of a row is taking the original row times the next row number
So for row 15, it will be 15 X 16, which is 240. To find the smallest number, we take 15-1, which is 14. So 14 X 2=28, then 240-28=212. 212 will be the smallest number.

So 212 +214 +216 +218 +220 +222 +224 +226 +228 +230 +232 +234 +236 +238 +240 will give you 3378
