The value of the 30th term is <em>-168</em><em />

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.

Thank you for your question! I hope this helped! Have an amazing day and feel free to let me know if you have nay further questions! :D

guapka [62]

Answer:

Total pencils: 17

Total rulers: 15

Step-by-step explanation:

"I will buy 15 pencils."
