Answer:

Step-by-step explanation:
Let us consider the given terms one by one:
First term,
= 6
Second term, 
Difference between First and Second term = 2 - 6 = -4
Third term,
= -2
Difference between Second and Third term = -2 - 2 = -4
Fourth term,
= -6
Difference between Second and Third term = -6 -(-2) = -4
Therefore, the common difference is:
= -4
Let the use the formula for
term of an arithmetic sequence:

Putting the values of
and
:

Therefore, the
term is:
