6, 20, 8, 14, 10, 8, 12, … choose which pair of numbers comes next?

The answer is $\boxed{\text{B. }2, 18}$.

The sequence is generated by the following rule:

• Start with the numbers $6$ and $8$.
• Subtract $2$ from the first number and add $4$ to the second number.
• Repeat steps 2 and 3.

Therefore, the next pair of numbers is $2$ and $18$.

Here is a table of the first few terms of the sequence:

Number | Rule | Value
——- | ——– | ——–
$1$ | $6$, $8$ | $6 – 2 + 4 = 8$
$2$ | $8 – 2 + 4 = 10$
$3$ | $10 – 2 + 4 = 12$
$4$ | $12 – 2 + 4 = 14$
$5$ | $14 – 2 + 4 = 16$
$6$ | $16 –
