The geometric mean is the average of a relevant set of quantities multiplied together to produce a product. The geometric mean of a collection of positive real numbers is the th root of the product of the numbers. So second geometric mean in sequence is In the given sum a = 1/8 , n = 4 and b = 128 G 2 = (1/8) ( 128 x 8) 2/5 G 2 = 2 Example-12: ‘x’ and ‘y’ are two numbers whose AM is 25 and GM is 7. If be the geometric mean of x and y, then Solution: 2. Know the right approach to handle the questions based on arithmetic and geometric mean. Geometric mean formula, as the name suggests, is used to calculate the geometric mean of a set of numbers. Find the numbers Solution So The geometric mean is defined as the nth root of the product of n numbers, i.e., for a set of numbers a1, a2, …, an, the geometric mean is defined as G.M = n If three geometric means be inserted between 2 and 32, then the third geometric mean will be (a) 8 (b) 4 (c) 16 (d) 12 Solution: 3. Word problems on sum of the angles of a triangle is 180 degree OTHER TOPICS Profit and loss shortcuts Percentage shortcuts Times table shortcuts Time, speed and … Note that if is even, we take the positive th root.It is analogous to the arithmetic mean (with addition replaced by multiplication) in the following sense: the arithmetic mean of two numbers and is the number such that , while the geometric mean of the numbers and is the number such that . Go through the solved examples to understand the concept in a better way. Geometric Mean Problems with Solutions 1. >Geometric Mean The Geometric Mean is a special type of average. To recall, the geometric mean (or GM) is a type of mean that indicates the central tendency of a set of numbers by using the product of their values. An online statistical geometric mean calculator to find the geometric mean value of the given numbers or statistical data when Problem solving - use acquired knowledge to solve geometric mean practice problems Interpreting information - verify that you can read information regarding geometric means and interpret it correctly You will also know various tips to solve these
