Answer:
it's a geometric sequence. the explicit formula is: 8 times 1/2^n-1
Answer:
B. Geometric. [tex]f(n) =16\cdot \left(\frac{1}{2}\right)^{n}[/tex], [tex]\forall n \in \mathbb{N}_{O}[/tex]
Step-by-step explanation:
The problems shows a geometric sequence, since the statement describes succesive halves that are consumed by Achilles. The formula is:
[tex]f(n) =\Sigma_{i=1}^{n} 16\cdot \left(\frac{1}{2}\right)^{i}[/tex], [tex]\forall n \in \mathbb{N}[/tex]
