How to solve a series math
WebExample. Consider the geometric sequence 3, 6, 12, 24, 48, \ldots. Find a formula for a_ {n} and use it to find a_ {7}. Solution. To find r, we should look at the ratio between successive terms: r= \frac {a_ {1}} {a_ {2}} =\frac {6} {3} = 2. Then using the formula above we get a_ {n} = r^ {n-1} a_ {1} = 2^ {n-1} \cdot 3 . WebAnd, as promised, we can show you why that series equals 1 using Algebra: First, we will call the whole sum "S": S = 1/2 + 1/4 + 1/8 + 1/16 + ... Next, divide S by 2: S/2 = 1/4 + 1/8 + 1/16 …

Since we get the next term by multiplying by the common ratio, the value of a2 is just: a2 = ar Continuing, the third term is: a3 = r ( ar) = ar2 The fourth term is: a4 = r ( ar2) = ar3
WebA geometric series is the sum of a geometric sequence. Thus, with the series you just see if the relationship between the terms is arithmetic (each term increases or decreases by adding a constant to the previous term ) or geometric (each term is found by multiplying the previous term by a constant).
