To describe the pattern of the sequence, we need to find the change that occurs between each consecutive term. Here, notice that the difference between each pair of consecutive terms in the sequence is adding 1.1. We can describe the pattern as the previous term added 1.1. 1.1→+1.12.2→+1.13.3→+1.14.4 To find the fifth and sixth terms, we have to add 1.1 twice. 1.1→+1.12.2→+1.13.3→+1.14.4→+1.15.5→+1.16.6
