Question

What is the value of the 30th term in the following arithmetic sequence? 12, 6, 0, -6, ... HELP!!!!

Answer 1

30 times by 6 because it goes down by 6 which is 180 and take awat from 12 which is -168
And don't forget that it is a negative. so leave a minus before the number.

Answer 2

The value of the 30th term is -168

According to our sequence, we are subtracting 6 every time. If we look at our number line though, we notice that we start 2 terms before we get to zero, so we an multiply our -6 by 28 because when we multiply we start from zero and the term we are wanting, our 30th term, is actually 28 terms away from zero. So:

-6 * 28 = -168

And this is our answer of the 30th term in the arithmetic sequence.
