Answer 1

I see the pattern of

times 2, minus 3, times 2, minus 3, and so on...

Answer 2

It is a pattern. 6*2=12; 9*2=18 15*2= (blank). What is the last answer to the problem. 15*2=?

Answer 3

\(\large\color{black}{ \bf 6 \times 2=12 }\)
\(\large\color{black}{ \bf 12-3=9 }\)
\(\large\color{black}{ \bf 9 \times 2=18 }\)
\(\large\color{black}{ \bf 18 -3=15 }\)
\(\large\color{black}{ \bf 15 \times 2... }\)
