We are required to write a JavaScript function that takes in a Number, say n, and finds the sum of the square of first n odd natural Numbers.

For example −

If the input number is 3. Then the output will be −

1^2 + 3^2 + 5^2 = 35

Therefore, the output is −

35

Following is the code −

const num = 3; const squaredSum = num => { let sum = 0; for(let i = 1; i <= num; i++){ sum += Math.pow((2 * i) - 1, 2); }; return sum; }; console.log(squaredSum(num));

Following is the output in the console −

35
