Determine whether the sequence is arithmetic. If it is, determine the common difference. --12, 10, 32, 54,...

The sequence is arithmetic

Step-by-step explanation:

Here we want to determine the sequence is arithmetic

If the sequence was arithmetic, the difference between the terms would be constant

We have this as;

10-(-12) = 22

32-10 = 22

54-32 = 22

As we can see, the difference is constant and so we have it that the sequence is arithmetic
