# Calculating value of a sequence based on some input using JavaScript

JavascriptWeb DevelopmentFront End Technology

## Problem

We are required to write a JavaScript function that takes in a number n as the only input. Suppose a sequence u for which,

u1 = 0 and u1 = 2

Our function should find the of un for which,

6unun+1- 5unun+2+un+1un+2 = 0

## Example

Following is the code −

Live Demo

const num = 13;
const sequenceSum = (num = 1) => {
const res = Math.pow(2, num);
return res;
};
console.log(sequenceSum(num));

## Output

8192
