\displaystyle 32

Correct answer:

\displaystyle 31

Explanation:

To form the sequence, begin with the term 7. Each subsequent term is equal to 6 added to the previous term, as follows:

\displaystyle 7+ 6 = \textbf{13}

\displaystyle 13+ 6 = \textbf{19}

\displaystyle 19+6 = \textbf{25}

\displaystyle 25+ 6 = \textbf{{\color{Red} 31}},

the missing term.
