A power series is expressed in summation notation:\[\sum_{0}^{\infty} a _{n}\] Above is an example of how a power series is expressed... Now, in order to make it fit this description, you have to recognize a pattern in your function. For example, the sequence {1,2,4,8,16,32} always increases by a multiple of 2. Therefore, you can make this sum: \[\sum_{0}^{5} 2^{n}\] If you have anymore questions, ask away!

how would you take a function, such as 1/2+x, and represent it as a power series?
