# Sum Of Consecutive Numbers Calculator

Consecutive integers are numbers that follow each other in order. The difference between the two consecutive numbers is one. If n is an integer, then n, n+1 and n+2 would be its consecutive integers. This online sum of consecutive numbers calculator is used to find the addition of consecutive numbers. Adding consecutive integers can be done by just entering the starting and ending number in the calculator. Summing can be done manually using the formula n ( n + 1 ) / 2.

#### Formula:

Sum from a to b Inclusive = T(b) - T(a) + a
T(b) - T(a) + a = (b + a) x (b - a + 1) / 2
**Where,**
c = Consecutive Integer Sum
a = Value of n1
b = Value of n2

#### Example

**
Find the sum of Consecutive numbers of 1 to 100?**

= ((100+1)*(100-1+1))/2

The equivalent sum of consecutive integer is 5050.
