This is the second half of a lesson, watch the first half here: http://youtu.be/yudhkUUzAgY This is a well-known and hugely controversial result. The "proof" I've demonstrated is not the only way to show it - there are far more sophisticated and convincing ways to do it - but suffice to say that I went through it to raise questions and provoke thought rather than to make a statement about its validity or otherwise! Hope it makes you think.

http://ItsMyAcademy.com/arithmetic-sequences/ For Free Complete Video Tutorial on Sequence & Series. For more videos on sequence and series. To Find the sum of odd numbers we have to first make an arithmetic sequence or arithmetic series then we can easily find the sum of odd numbers from sum of n term formula of arithmetic sequence. its is simple . In this video we are dealing with such problems. Here we need to find the sum of odd numbers from 0 to50 using the sum of n term formula of arithmetic sequence. To do so we will first arrange the all odd numbers between 0 to 50 in increasing order then taking 1 as first term and 49 as last term we will make an arithmetic series. By using nth term formula of arithmetic sequence we will get the total number of terms of the sequence and then by ...
The two numbers calculated here are 16 and 16. I think we should be more specific, and therefore, the question is extended include two different integers and then the answer should be 15 and 17. Their sum is 32 and product is 255. NOTE: At times it may be important to explain our answer, along with assumptions, even in the test paper. This video is included for your suggestions and views. Thanks!
In this video we will learn how to find two numbers whose sum is 27 and product is 182. Subscribe to our Youtube channel to keep receiving more Math learning videos. On Facebook : http://www.facebook.com/GuruBix Watch more videos on : http://www.gurubix.com
Understanding the logic behind the formula develops critical thinking skills. Even the most complex math problems seem simple when solved using logic. This other side of math is rather fascinating.
