The common difference for this arithmetic sequence will be 5.Option B is correct.
An arithmetic sequence is a set of integers where each of the terms differs from the ones next to it by one.
The arithmetic sequence is as follows if the first term in a series is "a" and the common difference is "d":
a, a + d, a + 2d, ... , a + (n+1)d, ...
The common difference in this arithmetic sequence is;
⇒d=-1-(-6) = -1+6 = 5
⇒d=4-(-1) =5
⇒d=14-9 =5
The common difference for the sequence is 5.
Hence,option B is correct.
