The rule "Multiply by 3" is used to generate a pattern. The pattern starts at 4. What is the fifth number in the pattern?

O 60
O 108
O 216
O 324

The fifth number in the pattern can be found by multiplying each number in the pattern by 3.

Starting at 4:
4 x 3 = 12 (first number in the pattern)
12 x 3 = 36 (second number in the pattern)
36 x 3 = 108 (third number in the pattern)
108 x 3 = 324 (fourth number in the pattern)
324 x 3 = 972 (fifth number in the pattern)

Therefore, the fifth number in the pattern is 972.
