Electromagnetism Part 2: More examples, solved problems and Quizzes related to Electromagnetism,Magnetic dipoles, Induction, Induced EMF

You can boost up your problem solving on arithmetic and geometric progressions through this wiki. Make sure you hit all the problems listed in this page.

This section contains basic problems based on the notions of arithmetic and geometric progressions. Starting with an example, we will head into the problems to solve.

An arithmetic sequence is a sequence of numbers in which each term is given by adding a fixed value to the previous term. For example, -2, 1, 4, 7, 10,. is an arithmetic sequence because each term is three more than the previous term. In this case, 3 is called the * common difference* of the sequence. More formally, an arithmetic sequence is defined recursively by a first term and for , where is the common difference. Explicitly, it can be defined as.

To find the term in an arithmetic sequence, you use the formula where is the term, is the first term, and is the difference between consecutive terms.

Here we will learn to solve the three important types of word problems on arithmetic mean (average). The questions are mainly based on average (arithmetic mean), weighted average and average speed.

1. The heights of five runners are 160 cm, 137 cm, 149 cm, 153 cm and 161 cm respectively. Find the mean height per runner.

Of the original seven Millennium Prize Problems set by the Clay Mathematics Institute , six have yet to be solved, as of 2017: [10]

The seventh problem, the Poincaré conjecture , has been solved. [11] The smooth four-dimensional Poincaré conjecture —that is, whether a four-dimensional topological sphere can have two or more inequivalent smooth structures —is still unsolved. [12]

if the sum of the 8th and 9th terms of an arithmetic progression is 72 and the 4th term is -6, find the common difference.

first term a And 9th term a+8d sum of these terms is 2a+8d=24 ie a+4d=12 sum of the first 9 numbers is 9/2(2a+8d) ie 9/2(2(a+4d))ie 9/2(2.12)ie 108
