Note that you are subtracting 6 each time.

5 terms have been shown.

Multiply -6 with 7 (as you are trying to find the 12th term)

-6(7) = -42

Add - 42 with -25

(-42) + (-25) = -67

(D) -67 is your answer

hope this helps

In order to solve, we must use the formula: [tex] a_{n} = a_{1} + (n-1)d [/tex]

a1 is the first term, n is the term position, and d is the common difference. We know that the first term is -1, the position we are trying to find is the 12th, and the difference is -6. So plug them all in.

[tex] a_{12} = -1 + (12-1)(-6) [/tex]

So (12-1) = 11 and 11 (-6) = -66 now subtract 1

Answer is -67
