Answer:
Not an arithmetic sequence
Step-by-step explanation:
For the sequence to be arithmetic there must be a common difference between consecutive terms.
- 7 - (- 3) = - 7 + 3 = - 4
- 10 - (- 7) = - 10 + 7 = - 3
- 14 - (- 10) = - 14 + 10 = - 4
The differences are not common , hence not an arithmetic sequence
Answer:
Not arithmetic and no common difference.
Step-by-step explanation:
Arithmetic sequence is a sequence of numbers increasing or decreasing in a constant form. That is where the common difference come.
To get the common difference to determine if it is arithmetic, you subtract the values like this: n₂ - n₁ = n₃ - n₂ = n₄ - n₃ and so on.
So,
-7 - (-3) = -4
-10 - (-7) = -3
-14 - (-10) = -4
As you can see, there is one set of numbers that result to -3 while the others are -4. They are not arithmetic and do not have a common difference.
