Answer: 1) 2, 3, 4, 9, 32, 279, 8896, 2481705, 22077238784
2) 2,490,924
3) Neither
<u>Step-by-step explanation:</u>


Neither
Not arithmetic because the difference between each of the terms is not the same.
S₂ - S₁ S₃ - S₂ S₄ - S₃
3 - 2 = 1 4 - 3 = 1 9 - 4 = 5
Not geometric because the ratios between each of the terms is not the same.

-39, -37, -35, -33, -31, -29. Odd numbers are the same just backwards ;)
Answer:
$233.75
Step-by-step explanation:
2.75 x 15 = 41.25
275 - 41.25 = $233.75
(3, -2) satisfies both equations. 3-2=1, and -3-2=-5.
