This is for pre-calc, so use pre-calc terms. you do not have to answer number 1. i have it done already. i need asap to get this done. i am giving 50 points to the first person who answers the questions right.

1) explain the major steps for doing a mathematical induction problem. walk through one of the example problems from the lesson or e-textbook as if you are teaching it to me.
2) for a given sequence: a1 = 2 a7 = 128 find a10 if it is an arithmetic sequence. find a10 if it is a geometric sequence. (the 2 will be different)
3) write the following two sequences using summation notation: 5 - 10 + 15 - 20 + 25 - 40 5 - 10 + 15 - 20 + 25 - (hint: these are different)
4) find an equation for the nth term in the following sequence: 2, 8, 32, 128,
5) describe when to use a series and when to use an equation. for example, when would you use: f(x) = 3x+5 and when would you use: height = 2 + 3n (where n is 1, 2,
