Increasing Sequence: Also known as
An increasing sequence is also known as an ascending sequence.

Some sources refer to an increasing sequence which is not strictly increasing as non-decreasing or monotone non-decreasing.

Some sources refer to an increasing sequence as a monotonic increasing sequence to distinguish it from a strictly increasing sequence.

That is, such that monotonic is being used to mean an increasing sequence in which consecutive terms may be equal.

does not endorse this viewpoint.
