Given numbers: -250 and 138, 136 and -272.

According to the given question:
The sum of -250 and 138:
= - 250 + 138
= -112


Now, finding the sum of 136 and -272, we have:
= 136 + (– 272)

= 136 - 272 ...[(-) x (+) = -]

= - 136


Now, by subtracting (- 112) from (- 136), we get:
= -136 - (-112)

= - 136 + 112...[(-) x (-) = +]

 = - 24


Therefore, the required number is - 24.
