- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Example:

n - 3

n = 5

- - - - - - - - - - - - - - - -

n - 3

5 - 3 = 2

five minus three equal two

Look at your definition of the ratio test. Limit from n to infinity of the absolute value of the series defined at n+1 over the series defined at n. So fill in the blanks for all of that first. It should look like lim(n -> inf) of the abs. value of ((n+1)! / 3^(n+1)) / (n! / 3^n) Now simplify that statement. On the numerators, n! is 1*2*3*...*n, (n+1)! is 1*2*3*...*n*(n+1), so all terms cancel except (n+1). On the denominators, 3^n is 3*3*3*... n number of times. 3^(n+1) would be 3*3*3*... (n+1) number of times. Meaning you've got one more for the 3^(n+1), all the others cancel, leaving 3 on the denominator. This results in (n+1)/3. Take the limit as n goes to infinity, gives you infinity / 3, which is infinity. When the ratio test turns out larger than 1, the series diverges. Pay attention to the definitions in your textbook for these tests, they are important, but most are simple - fill in the blanks and simplify. What calculus class is this for? I don't remember seeing this until I was in multivariable calculus.

Answer 4

n belongs to Cardinal Numbers, and n+1 means u have to think that 1 will add to n
