How to get almost increasing sequence of integers

Given a sequence of integers as an array,i have to determine whether it is possible to obtain a strictly increasing sequence by removing no more than one element from the array. Example

For sequence = [1, 3, 2, 1], the output should be

almostIncreasingSequence(sequence) = false

There is no one element in this array that can be removed in order to get a strictly increasing sequence.

For sequence = [1, 3, 2] the output should be

almostIncreasingSequence(sequence) = true

We can remove 3 from the array to get the strictly increasing sequence [1, 2]. Alternately, we can remove 2 to get the strictly increasing sequence [1, 3].

The function must return true if it is possible to remove one element from the array in order to get a strictly increasing sequence, otherwise return false.

Here is what i have already tried , but it doesnt work for all situations

function almostIncreasingSequence(sequence) {
    for (var i = 0; i < sequence.length; i++) {
        if (sequence[i] > sequence[i + 1]) {
            sequence.splice(i, 1);
           return true;
        };
        return false;
    };
}

Answer

Here is my answer

function almostIncreasingSequence(sequence) {
    if (isIncreasingSequence(sequence)) {
        return true;
    }



    for (var i = 0; i < sequence.length > 0; i++) {
        var tmpSequence = sequence.slice(0); // copy original array

        tmpSequence.splice(i, 1);
        if (isIncreasingSequence(tmpSequence)) {
            return true;
        }
    }

    return false;
}

function isIncreasingSequence(sequence) {
    for (var i = 0; i < sequence.length - 1; i++) {
        if (sequence[i] >= sequence[i + 1]) {
            return false;
        }
    }

    return true;
}

almostIncreasingSequence([1, 3, 2, 1]); // false
almostIncreasingSequence([1, 3, 2]); // true
