Answer: B)-4
Step-by-step explanation:
In Arithmetic sequence , the common difference is the difference between any two successive terms. It is equal throughout the sequence.
Given arithmetic sequence : 51, 47, 43, 39, ...
Here , First term = 51
Second term = 47
Then the common difference = Second term - First term
i.e. Common difference = 47-51 =-(51-47)=-4
Hence, the common difference between consecutive terms in the following arithmetic sequence= -4
Thus , the correct answer is option B)-4 .
