$x+(x+1)+(x+2)+(x+3)+(x+4) = 100$

solve for $x$

Let the first number be $x$, then the second will be $(x+1)$, the third $(x+2)$ ...

Set the sum of the numbers equal to 100...

Let $x$ be the smallest of the five consecutive numbers whose sum is 100.

The number after $x$ is $x + 1$.

The number after $x + 1$ is $x + 1 + 1 = x + 2$.

The number after $x + 2$ is $x + 2 + 1 = x + 3$.

The number after $x + 3$ is $x + 3 + 1 = x + 4$.

These are our five consecutive numbers.

We are told their sum is 100. Therefore, $x + x + 1 + x + 2 + x + 3 + x + 4 = 100$.

Combine like terms.

$5x + 10 = 100$

Subtract 100 from both sides of the equation.

$5x = 90$

Divide by 5 on both sides of the equation.

$x = 18$
