Question

What is the common difference for the sequence shown below? coordinate plane showing the points 1, 3; 2, 5; and 3, 7

a. −2
b. −one third
c. one third
d. 2

Answer 1

D

Explanation:

The common difference of sequence given in coordinate points is the difference in the y-values of the points.

Common Difference (d) = term y-value - previous term y-value

Thus, we can say, d = 5 -3 = 2, or even 7 - 5 = 2.....

Hence d = 2

Correct answer is D
