last page equation was 1/20 n (n-14), its actaully easy, i did this in order to get 1/p x 3 (3 - q) = 2, and solved like leaner equation and last question answer (last part) was 300
2nd variant n=3 was a triangle and total no. of diagnols was 0 & 2 was for n=4 may be u overlooked

ZiadOwns you answer to the formula is actually wrong so you last paper was all wrong the formula will be 1/2n(n-3) as p=2 and q=3 and the last question in sequence was 31 not 300
