Find Constant Differences

[USCBABY]

I am having trouble with these two questions :


Find the the next the three terms with the constant differences.

A. 1,4,7,10,13
B. 30,25,20,15,10

A. 1,4,7,10,13

Do you know what a "first difference" is? Just subtract successive values.

4-1 = 3
7-4 = 3
10-7 = 3
13-10 = 3
What - 13 = 3??
