What is the sum of all integers from:

12 to 15 inclusive?

Inclusive Sum = n/2(f + l)

where f is the first number and l is the last number and

n is l - f + 1

n = 15 - 12 + 1

n = 4

4/2(12 + 15)

2(27)

sum of inclusive integers from 12 to 15 = **54**

sum of inclusive integers from 12 to 15 = **54**
