Answer:
k = 4.
Step-by-step explanation:
An arithmetic sequence has a common difference.
So for this to be arithmetic:
k + 3 - (k - 1) = 3k - 1 - (k + 3)
k + 3 - k + 1 = 3k - 1 - k - 3
3 + 1 = 2k - 4
4 + 4 = 2k
k = 4.
The sequence is 3, 7, 11.
For 1. (Monday), it is rational. For 2. It is C. For 3. It is -15/24 (I am assuming, it isn’t clear), -2 2/5 (Assuming) and -0.95. 4. Is less than 1. The decimal it is 0.625. 5. 11/5 is greater than 1. The decimal is 2.2. For 6. It is equal to 1. 1 is 1.000 or 1. In decimal form. For 7. It is less than 1. The decimal is 0.571. It is only for Monday. I hope this helps!
