Answer: Yes, this is a geometric sequence.
Step-by-step explanation:
This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 3 gives the next term.
It would be C.88-x and there are 36 black keys on an 88 key piano
I think it's D. 58 because The triangle has a right angle (90 degrees), so all you have to do is subtract 32 from 90.
Answer: D. 58 degrees
Answer:
<h2>
100, -50, 25, -12.5, 6.25, -3.125, 1.5625, -0.78125</h2>
Step-by-step explanation:
Each term is being multiplied by <u>-0.5</u>
How did I know?
Divide the second term by the first.
-50 divided by 100 = -1/2
Find the last four terms.
-12.5 x -1/2 =<em> </em><u><em>6.25</em></u>
6.25 x -1/2 = <u><em>-3.125</em></u>
-3.125 x -1/2 = <u>1.5625</u>
1.5625 x -1/2 =<em><u> -0.78125</u></em>
