let numbersArray = []; // initialize an empty array

function processNumbers() {
    let defaultNumbers = [1, 2, 6, 7, 8, 1, 9, 6, 0]; // set default number values
    let initialTimeout = 10000; // set initial timeout value
    let additionalTime = 10000; // time to add for each iteration

    defaultNumbers.forEach(num => {
        setTimeout(function () {
            addToNumbersArray(num); // call function to push number to the array after set timeout
        }, initialTimeout);

        initialTimeout += additionalTime; // increment timeout for next number.
    });
}

function addToNumbersArray(num) {
    numbersArray.push(num);
    console.log(numbersArray);
}

processNumbers(); // start processing the numbers array
