Arithmetic, common difference is 7.
To find out if a sequence is arithmetic, we need to check if there is a constant difference between consecutive terms.
In this case, we have:
-17 - (-9) = -8
-26 - (-17) = -9
-33 - (-26) = -7
Since we don't have a constant difference here, the sequence is not arithmetic.
Tell whether the sequence is arithmetic. If it is, identify the common difference. -9, -17, -26, -33,
Not arithmetic
Arithmetic, common difference is 8
Arithmetic, common difference is 9
Arithmetic, common difference is 7
