Answer 1

We want to find the expression that represent the given pattern.

To determine this let us substitute 2 into each expression, the expression that gives the same value as the one in the pattern is the one that represent the pattern.

(at n=2, expression must be equal to zero)

`\begin{gathered} -3n=-3(2)=-6 \\ -3n+6=-3(2)+6=0 \\ n+2=2+2=4 \\ 3n=3(2)=6 \\ 6n-3=6(2)-3=9 \end{gathered}`

At n=2 only one expression gave us zero.

So, the only expression that represent the given pattern is;

`B.-3n+6`
