Question

Which of the following rules can be used to find the next term of the given pattern?

• A. Add $2$ to the previous term.
• B. Subtract $4$ from the previous term.
• C. Subtract $2$ from the previous term.
• D. Add $4$ to the previous term.

Answer 1

The correct option is A Add $2$ to the previous term.

We can observe that there are $1,3,5,$ and $7$ blocks in the first, second, third, and fourth terms of the pattern, respectively.
$3=1+2$
$5=3+2$
$7=5+2$
So, the consecutive terms in the pattern are found by adding $2$ to the previous term.
