SP8836 SEQ7 - Yet Another Sequence Problem

We have an infinite non-decreasing sequence A which is created as follows : - A\[1\] = 1 and A\[2\] = 2. - A number i occurs A\[i\] times in the sequence. First few terms in the sequence are: { 1, 2, 2, 3, 3, 4, 4, 4, 5, 5, 5, 6, 6, 6, 6, 7... }. Note that 3 occurs 2 times in the sequence, (because A\[3\] = 2). Your task is to find the term A\[n\] for any given n, where 0 < n
