Equal because 30 is the median and when you find the mean, it is also 30. Please give brainliest!
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.
M=3 because you divide 2.1 into 6.3 and i goes in to it 3 times
Can you add more information??
