the sequence.
a arithmetic; -23
b. arithmetic; -276
c. geometric; -23
d. geometric; -276​

Answer 1

a arithmetic; -23

Explanation:

this is not geometric sequence as we don't see multiplication effect in the terms

let's see what is the difference in terms

-207- (-184)= -23

-230- (-207)= -23

-253- (-230)= -23

we can state it is an AP with common difference of -23

option a. is correct
