In order to solve a negative exponent, you have to consider the multiplicative inverse of the base:
So, if we solve the negative exponent on the left hand side, we have
which is the right hand side.
First of all, find the first number more than 100 that can divided by 9, and it's 108 (we'll call it as 'a') then, find the number less than 2000 that can divided by 9, it's 1.998 (we'll call it as 'Un')
Un = a + (n-1).b
1998 = 108 + (n-1).9
1998 = 108 + 9n -9
1899 = 9n
211 = n
and the total is
Sn = n/2 (a+un)
s211 = 211/2 (108+1998)
= 222.183
