Name the next three terms in the sequence: 6,8,-32,-30,120

I first tried and got 122, -610 and -608. Supposedly the first number is right but not the next? I hope someone can help soon!

\(A_2=A_1+2\\ A_3=A_2\cdot(-4)\\ A_4=A_3+2\\ A_5=A_4\cdot(-4)\\ \)

For the next term, you take 120 and add two to get 122.

Then, you multiply by -4 to get -488.

Finally, you add two again to get -486.

The next three terms in order are 122, -488, -486.

Thanks so much!
