• no

Compare the patterns: Pattern A: 3, 6, 9, 12 and Pattern B: 4, 8, 12, 16. Which pattern grows faster?

• Pattern A

• Pattern B

• Both grow at the same rate

• Cannot be determined

Answer explanation

Pattern A increases by 3 each time (3, 6, 9, 12), while Pattern B increases by 4 (4, 8, 12, 16). Since Pattern B has a larger increment, it grows faster than Pattern A.
