Answer:

yes; 5

Step-by-step explanation:

To determine if the sequence is arithmetic, take the second term and subtract the first term

-7 - (-12) = -7+12 = 5

This would be the common difference if our sequence is arithmetic

Now take the second term and add the"common difference"

-7+5 = -2  This is our third term

-2+5 = 3  This is our fourth term

The sequence is arithmetic with a common difference of 5

A: 6/8, 9/12, 12/16
b: 6/14, 9/21, 12/28
c: 6/9, 2/3, 4/6
d: 1/4, 2/8, 2/12

In order to find equivalent fractions for a fraction is multiply or divide the numerator and denominator by the same number.

For example, 3/4=6/8 because 3x2=6 and 4x2=8, 6/8.

Hope this helps!
