Question

The rule for the pattern is add one column. What are the next three terms? (3 points) An image of a pattern. Term one has six dots, term two has eight dots, and term three has ten dots. a 15, 20, 25 b 12, 14, 16 c 8, 10, 15 d 6, 8, 10

Answer 1

b 12, 14, 16

Explanation:

You want the next three terms of a sequence that starts 6, 8, 10, ....

Rule

The rule seems to be "add 2." If we continue to add 2 to each term, we find the next terms to be ...

10 +2 = 12

12 +2 = 14

14 +2 = 16

The next 3 terms are 12, 14, 16.

Additional comment

Without the figure, the idea of "add one column" is meaningless. Since answers are in terms of dot counts, it would be more meaningful to describe the pattern in terms of what happens to the dot count.
