Two consecutive terms of a sequence usually is not enough. As a guess, numerator went down by 1 and denominator went down by 1. The next term might also do the same, so you could expect it to be 1%2F6.

This has nothing to do with sequence or series.
3/8+2/7<=1
21/56+18/56<=1
39/56<=1
ok
yes there is enough
