If the difference of AB and the difference of BC is 98 then what is the sum of AB and C?

If the difference of AB and the difference of BC is 98, it can be expressed mathematically as ( AB - BC = 98 ). To find the sum of AB and C, we need more information about the values of AB and BC. Without additional details about the relationships between AB, BC, and C, we cannot determine the exact sum of AB and C.
