Determine whether the sequence is arithmetic. If it is, find the common difference.
IMPORTANT. Please do not use spaces in writing your answer.
2, -4, 6, -8, 10, ...
Check if the differences between consecutive terms are equal?
10 - (-8) = ___
-8 - 6 = ___
6 - (-4) = ___
-4 - 2 = ___
Is the sequence 2, -4, 6, -8, 10, ... arithmetic or not?
Arithmetic Sequence
Not Arithmetic Sequence
If the sequence is arithmetic, find d. (If not arithmetic, type in NO D.)
Answer (1)
10 - (-8) =18-8 - 6 = -146 - (-4) = 10-4 - 2 = -6Not arithmetic so its no D and it is not a sequence
