If there are four seats per row, one person sits at each end, and two spaces will be between them. The same goes for 7 seats, namely the first, fourth, and seventh will be occupied. Continuing this way, we know that seats will be occupied on the

1st, 7th, 10th, 13th, .... (3n+1)th.

So which is the occupied seat below or equal to the 100th seat?
