To find the first term of the series, we need to plug in 2 for the n-value. Sigma Notation of a Series A series can be represented in a compact form, called summation or sigma notation. Finite geometric series in sigma notation. So when k equals 200, that is our last term here. To find the first term of the series, we need to plug in 2 for the n-value. When k is equal to 200, this is going to be 200 minus one which is 199. As mentioned, we will use shapes of known area to approximate the area of an irregular region bounded by curves. 2. Since there are five terms, the given series can be written as The general formula for an arithmetic sequence is a n = a 1 + (n - 1)d What is the difference between the fourth and the tenth terms of {2,6,10,14,...) We have a 10 - a 4 = (10 - 4)d = 6(4) = 24. Sigma (Summation) Notation. Arithmetic Series. To find the next term of the series, we plug in 3 for the n-value, and so on.
