![]() ![]() Question 4: Explain what is mean mathematically?Īnswer: Mathematically, mean is the average of a set of numbers, which we also know by the name arithmetic mean. Moreover, it is the ‘central’ value of a set of numbers that add up all the numbers then divided by the total numbers there are.Īnswer: In mathematics, the symbol of exclamation mark that is “!” is used as the factorial of an integer which is the product of all the integers below it down to one. Then, from the general term formula,Īnswer: Mean or arithmetic mean is the average of the number. ![]() ![]() First term, a =1 and the common difference, d = 3 – 1 = 2. Question 1: Find the arithmetic mean of the series 1, 3, 5,……(2n-1)Īnswer: A is the correct option. So either A.M = G.M or A.M > G.M Solved Examples for You If a is the first term, then b will be the (n+2) th term.Ī n = a + n \( \frac \) = 12.5 ![]() Let a and b be the two given numbers and A 1, A 2……A n be the arithmetic means between them. Multiple Arithmetics Means between Two Given Numbers You can download Sequence and Series Cheat Sheet by clicking on the download button below Where A = arithmetic mean, N = the number of terms and S = the sum of the numbers in the list.īrowse more Topics under Sequences And Series This average in arithmetic progression is called the arithmetic mean. So we can say that this term b is the average of the other two terms a and c. In the arithmetic progression, we know that if the three numbers are in AP, that means if a, b and c are in AP, then basically the first two terms a and b will have the difference which will be equal to the next two terms b and c. Let us first understand the concept of arithmetic progression. The sum of all of the numbers in a list divided by the number of terms in that list gives the arithmetic mean of that list. ![]()
