The answers are
a) 245314
b) (k2 + k- 72)/2
a)
Let F(n) denotes the sum of first n natural numbers.
F(n) = (n(n+1))/2
9+10+11+12+13+----------------------+700
F(700) - F(8) = (700*701)/2 - (8*9)/2 = 490628/2 = 245314
b)
9+10+11+-------------------k
F(k) - F(8) = (k(k+1))/2 - (8*9)/2 = (k2 + k- 72)/2
