Hello everyone, I am working through a program and stuck on a challenge and cannot figure out why this will not work [duplicate]

Task: Use a for loop to iterate through the array and increase each number by two.

const increaseByTwo = [1, 2, 3, 4, 5];

What is wrong with my code here?

for (let i = 0; i < increaseByTwo.length; i+=2){ 
  
}
