Use the arithmetic progression formula to find the sum of integers from 75 to 100.75,76,7799,100.​

The sum is 2275

Step-by-step explanation:

Given

Required

The sum

Using arithmetic progression, we have:

Where:

--- first term

--- last term

So, we have:

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.
