the answer is A.
the equation is f(n-1)+2. f is -6 and n is the number of term. so for example, if you want to find the second term, you substitute n for 2. then you solve.
-6(2-1)+2,
-6(1)+2,
-6+2= -4. therefore the second term is -4. you do this with n being 1,3,4,5 to get the sequence of
2, -4, -10, -16, -22.
hope this helped !!
