Explanation
Two sequences are interleaved: the terms in the odd positions run 1, 2, 3, 4 and those in the even positions run 4, 5, 6, 7, each rising by one. The next term sits in an odd position, so it continues the first sequence after 4, giving 5. Splitting an irregular looking series into alternate terms is the standard first move.
