Question

Please help i really need to get this done

Write an equation for the n th term of the arithmetic seqeuence. Then find a 10
-6, – 9. - 12. - 15, .

Answer 1

3n-9

Explanation:

Each term increases by 3, so there n should be multiplied by 3.

If the first term (or when n = 1) is -6 and we have 3n, we need to subtract 9 to get -6. This also works for the other terms in the sequence.

The 10th term of the sequence would then be:

3(10)-9
