How would you find the limit as x goes to infinity of

1 + (-1)^x
----------------
x

My book says it's 0, but I don't know why. When I look at it, I see 1 - infinity divided by infinity--not sure how to simplify that....

thanks

Here are some number sequences I thought up. See if you can find the next number, and also identify the pattern.

Sequence 1:
1, 3, 4, 7, 6, 12, 8, 15, 13, ?

Sequence 2:
100, 19, 83, 34, 70, 45, ?

Sequence 3:
1, 1, 0, -1, 0, 7, 28, 79, 192, ?

Sequence 4:
2, 5, 10, 17, 28, 41, 58, 77, 100, ?

The numbers in the sequence may or may not depend on the previous number.

Can anyone prove this using mathematical induction:
1^3+2^3+…+n^3 = n(n+1)……..^2
……………………---------
………………………..2
for all integers n >=1.

Note n(n+1) / 2 are in brackets and than all that is squared by 2 (^2).

After several cakes that came out of the same cake pan were burned, George concluded that if he baked another cake in the same cake pan it would likely come out burned.

Is this an example of inductive reasoning or deductive reasoning????

I'm not asking you to solve it for me, I just wanted to ask if you're suppose to do this with a calculator, or you can do it without one. Because if you use a calculator it'd be super easy, whereas without me a bit tough
