Question

Observe the following pattern, and complete the correct statement that explains it.

Pattern A (subtract 2)	$20$	$18$	$16$
Pattern B (subtract 2)	$40$	$38$	$36$

Each value in pattern B can be found by ______ the corresponding values in pattern A.

• A. dividing $20$ by
• B. adding $20$ to
• C. multiplying $20$ by
• D. subtracting $20$ from

Answer 1

The correct option is B adding $20$ to

The first value in pattern A is $20$, and pattern B is $40$.
So, we can observe that by adding $20$ to $20$, we get $40$.

The second value in pattern A is $18$, and pattern B is $38$, which is obtained by adding $20$ to $18$.

The third value in pattern A is $16$ and pattern B is $36$, which is obtained by adding $20$ to $16$.

So, each value in pattern B can be found by adding $20$ to the corresponding value in pattern A.

Option D is correct.
