I'm studying Arithmetic Sequences and Geometric Sequences and I'm a little confused as to how I would figure out a few of the following problems. Any assistance would be appreciated!

Find the 7th term of the given sequence an = n(n + 2).

Find the first four terms of the given sequence an = (-1)n(n).

Find the 10th term of the given sequence an = (-1)n+1/n

and finally,

Find a formula for an, so that the first four terms are -1/2, ¼,-1/8, 1/16.

Again, any help is appreciated! Thanks!

I don't necessarily need the answers, moreso a method to solve the problems so that I understand the material. Thanks again!

The conductance of a wire varies directly as the square of the wire's diameter and inversely as its length. Fifty meters of wire with a diameter 2 mm has a conductance of 0.12 ohms. If a wire of the same material has length of 75 m and diameter of 2.5 mm, what is its conductance?

Use The Formulas for converting the unites for temperature to solve the problems.

C: Celsius ( C)
F: Fehrenheit (F)

To Convert Celsius To Fehrenheit
F= 9 / 5C + 32 the 9/5 is a fraction

To Convert Fehrenheit To Celsius
C=(F - 32) x 5 / 9 the 5/9 is a fraction

What is the temperature if Fenhereit if

a. It Is 20"C?
b. it is -15 C?

What is The temperature in Celsius if
a. it is 50 F?
b. It is 23F
