# Check three consecutive numbers - JavaScript

We are required to write a JavaScript function that takes in a Number, say n, and we are required to check whether there exist such three consecutive natural numbers (not decimal/floating point) whose sum equals to n.

If there exist such numbers, our function should return them, otherwise it should return false. Following is the code −

## Example

const sum = 54; const threeConsecutiveSum = sum => { if(sum < 6 || sum % 3 !== 0){ return false; } // three numbers will be of the form: // x + x + 1 + x + 2 = 3 * x + 3 const residue = sum - 3; const num = residue / 3; return [num, num+1, num+2]; }; console.log(threeConsecutiveSum(sum));

## Output

Following is the output in the console −
