Solution:

Don’t calculate! The number of terms in the set in Quantity A is

{98}/2

= 49. The number of terms in Quantity B is

{98}/2+1

= 50. Each term in Quantity A is one more than the corresponding term in Quantity B, Thus, up until 98, the sum of the terms in Quantity A is 49 greater. However, this is offset by the additional 99 in Quantity B. Thus, Quantity B is greater.
