Write an explicit formula for the sequence 8, 4, 0, -4, -8,
then find the 10th term in the sequence.

an = 8 - 4(n - 1).

10th term = -28.

Step-by-step explanation:

This is an arithmetic sequence with common difference -4.

an = 8 - 4(n - 1) is the explicit formula.

The 10th term =  8 - 4(10-1)

= -28.

21

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
