Answer:
Step-by-step explanation:
Alright, lets get started.
Arithmetic sequence is when a certain number is added in each term to get the next term of sequence.
The first term is given as -20 in option B
When we add -7 in it, we will get -27
When we add -7 in -27, we will get -34
When we add -7 in -34, we will get -41
When we add -7 in -41, we will get -48
It means this is a arithmetic sequence with common differnce -7.
hence the sequence is -20, -27, -34, -41, -48 : Answer
