Sorry, I didn't use fraction strips but,
2. 2/4
3. 4/6
4. 6/8
5. 1 is equivalent to 3/3 based on this problem so the answer is 1/3
6. 6/10
7. 2/4
8. 2/6
Hope this helped even without fraction strips! :)
Answer:The answer would be b
Step-by-step explanation:
Looks like your function is

Rewrite it as

Recall that for
, we have

If we replace
with
, we get

By the ratio test, the series converges if

Solving for
gives the interval of convergence,

We can confirm that the interval is open by checking for convergence at the endpoints; we'd find that the resulting series diverge.
