There is a common difference of $32$ therefore the given terms form an arithmetic sequence.
The given terms can be terms of an arithmetic sequence if there is a common difference among consecutive terms. Determine the difference between each pair of consecutive terms to obtain: $68-100=-32; \\36-68=-32; \\4-36=-32$ There is a common difference of $32$ therefore the given terms form an arithmetic sequence.
