How to add elements together using forEach

I'm struggling to complete this forEach practice. How do I write the logic to add the previous number to the next number in the array?

app.js 
const numbers = [1, 2, 3, 4, 5];
let total = 0;

// Write loop here:
numbers.forEach((number, index) => {
  total = number + ;
});

You are so close!

If you try this construct it will work:

numbers.forEach((number, index) => {
  total += number;
});

Good luck with JavaScript, it is an amazing language!
