Let the first term be a(0). Then the formula for a(n) is a(0)-18(n-1).
Check: What's the first term? Let n = 1: a(1) = a(0)-18(1-1) = a(0) (correct)
What's the second term? Let -n =2: a(2) = a(0)-18(2-1) = a(0) - 18
and so on.

Answer:
4x^2+4x-4
Step-by-step explanation:
8x^2 + 3x - 4x^2 + x - 4
= 8x^2 - 4x^2 + 3x + x - 4
= 4x^2 + 4x - 4
Answer:
≈ 268 or 85.3π
Step-by-step explanation:
V = 1/3πr²h
V = 1/3 x 3.14 x 4² x 16
V ≈ 267.9467 or 268
also can be considered 85.3π
Hi there!
The formula for a square is V = s^3. Using this formula, we can plug in the volume and solve for s.
WORK:
