Puzzle:

There are two friends A and B playing a simple game of putting ‘+’ or ‘-‘ sign between any two numbers written from 1 to 100 on a blackboard. They can put any sign between any two numbers as long as there is no sign placed between the two numbers. Once all the signs (a total of 99 signs will be there) have been put, the result is calculated. If it is even, then A wins and if it is Odd, then B wins. Who will win?

Solution – From the numbers 1 to 100, there are 50 odd numbers and 50 even numbers. It does not matter if ‘+’ or ‘-‘ sign is put between two odd numbers or two even numbers or one odd number and other even number. The net result is not going to be decided by the number of ‘+’ sign or ‘-‘ sign; it is going to be decided by the total number of odd numbers.

Resultant of 50 odd numbers = Even Number

Resultant of 50 Even numbers = Even Number

Hence net result = Even Number ± Even Number = Even Number. Hence A will always win.

Questions on ‘Series’ expect students to analyze the pattern of the numbers / letters given, and extrapolate on the basis of the rule or pattern identified. There are different types of rules in a series. Some of those are listed below:

1. The Difference Series:

In these types of series, pattern would be obtained by finding the difference between terms. Differences are categorized as 1^st order difference, 2^nd order difference, 3^rd order difference and so on.

What is the “Order of Difference”:

Let us understand this with the help of some examples:

1^st Order difference is the difference between two consecutive terms of the series. If 1^st order difference is constant, then general term of the series will be a Linear Equation.

2^nd Order Difference is the difference between the consecutive terms obtained from the 1^st order difference. If 2^nd order difference is constant, then general term of the series will be a Quadratic Equation.

And so on, 3^rd Order Difference will be difference between the consecutive terms obtained from the 2^nd order difference. If 3^rd order difference is constant, then general term of the series will be a Cubic Equatio...
