Answer: The common difference is 6.
Step-by-step explanation:
Since we have given that
14,8,2,−4,−10,…
It is an arithmetic sequence.
So, Here, a = first term = 14
d = common difference
As we know the formula for "Common difference ":
\(d=a_2-a_1\\\\d=8-14\\\\d=-6\\\\Similarly,\\\\d=a_3-a_2\\\\d=2-8\\\\d=-6\)
so, the difference is common.
Hence, the common difference is 6.
