The difference between the sum of 6 integers whose average is x and the sum of 3 numbers whose average is 2x-2 is?

The sum of the integers given the number of integers and their average is calculated by multiplying the number and the average. This is mathematically expressed as below,

Sum = (n) (m)

where n is the number and m is the average or mean.

For the first set,

Sum = (6) (x) = 6x

For the second set,

Sum = (3) (2x - 2)

= 6x - 6

If we are to subtract the second sum from the first,

Difference = (6x) - (6x - 6)

= 6x - 6x + 6

Hence, the answer is 6.
