Question

One pattern starts at 0 and has the rule "add 8." Another pattern starts at 0 and has the rule "add 4." Which of the following sets of ordered pairs represents the first 4 ordered pairs of the pattern?

A. (0, 0), (1, 8), (2, 16), (3, 24)
B. (0, 0), (1, 4), (2, 8), (3, 12)
C. (0, 0), (1, 10), (2, 20), (3, 30)
D. (0, 0), (1, 6), (2, 12), (3, 18)

Answer 1

The first pattern increases by 8 and the second pattern increases by 4. Option A represents the first 4 ordered pairs of the first pattern.

Step-by-step explanation:

The first pattern has a rule of 'add 8', which means that each number in the pattern is obtained by adding 8 to the previous number. Starting from 0, the pattern would be 0, 8, 16, 24.

The second pattern has a rule of 'add 4', which means that each number in the pattern is obtained by adding 4 to the previous number. Starting from 0, the pattern would be 0, 4, 8, 12.

Therefore, the set of ordered pairs that represents the first 4 ordered pairs of the first pattern is (0, 0), (1, 8), (2, 16), (3, 24), which corresponds to option A.
