What formula should I use for this?

1 answer:

8 0

If they're asking for the nth term, you should use n in your formula, ie.,

a(n) = 6000 * 0.5ⁿ

However, the first term is when n=1, so your formula should really be:

a(n) = 6000 * 0.5⁽ⁿ⁻¹⁾

Then the 8th term is 46.875

Step-by-step explanation:

Step 1: Define

(3x² + 2y² - 3x) + (2x² + y² - 2x) - (x² + 3y² + x)

Step 2: Simplify

[Distributive Property] Distribute negative: 3x² + 2y² - 3x + 2x² + y² - 2x - x² - 3y² - x
Combine like terms (x²): 4x² + 2y² - 3x + y² - 2x - 3y² - x
Combine like terms (y²): 4x² - 3x - 2x - x
Combine like terms (x): 4x² - 6x
