Consider the sequence 22, 5,7,2, 23, 10, 15, 21, 3, 17. Recall that every sequence of n2+1 distinct real numbers contains a subsequence of length n + 1 that is either strictly increasing or strictly decreasing. How many strictly increasing subsequences of length n 1 are there for the given sequence? 0 9 O 10! 4 0 8 0 10 None of these answers
