A sequence (Xn) in a metric space X is said to be strictly increasing if for all n?

A sequence (Xn) in a metric space X is said to be strictly increasing if for all n?

Explanation

The correct answer is: Xn < X(n+1)

A sequence (Xn) in a metric space X is said to be strictly increasing if for all n, Xn is less than X(n+1), denoted by Xn < X(n+1). This means that each term of the sequence is strictly greater than the previous term.
