It’s similar to D because they are going to have the same measured angle
I do not see a picture sadly.
Answer:
No, the given sequence is not arithmetic.
Step-by-step explanation:
The given sequence is

The first term is 5.
A sequence is an arithmetic, if the difference between any two consecutive terms are same.
