Question

Statement 1: The rule in Pattern $1$ is “subtract $1$ from the previous term.”
Statement 2: The rule in Pattern $2$ is “add $3$ to the previous term.”

Which of the following is correct?

• A. Both statements are incorrect.
• B. Both statements are correct.
• C. Only statement $1$ is correct.
• D. Only statement $2$ is correct.

Answer 1

The correct option is B Both statements are correct.

Pattern 1:
$10-1=9$
$9-1=8$
$8-1=7$
$7-1=6$
We can observe that each consecutive term in the pattern is found by subtracting $1$ from the previous term.

Pattern 2:
$4+3=7$
$7+3=10$
$10+3=13$
$13+3=16$
$16+3=19$
We can observe that each consecutive term in the pattern is found by adding 3 to the previous term.

Hence, both statements are correct.
