What are Odd and Even numbers?
An creature that have the right to be split by 2 is an even number, while an integer that cannot be separated by 2 is an odd number. They can be either positive or negative. Odd numbers are always in in between the even numbers and also vice versa.
You are watching: Are negative numbers even or odd
To differentiate between the odd and also even numbers, you constantly look because that their end digit. The critical digit of an also number is always 0, 2, 4, 6, or 8, while the last digit of one odd number is constantly 1, 3, 5, 7, or 9.
A few examples of also numbers are:
-22, -10, 0, 6, 18, 234.
The above numbers room even because they finish with 0, 2, 4, 6, or 8.
A couple of examples of odd number are:
-101, -17, 1, 9, 23, 985.
The above numbers space odd since they end with 1, 3, 5, 7, or 9.
The odd and even numbers have special properties concerning algebraic operations (addition, subtraction, and also multiplication). Whenever we apply algebraic operations to two also or strange numbers, we constantly get an also or strange number. We exclude department here since the division sometimes provides you the an outcome in fountain while talking about special properties.When we include or subtract two even numbers, the an outcome is constantly an even number.For example,6 + 4 = 10
6 – 4 = 2When we add or subtract an even number and an weird number, the result is always odd.For example,7 + 4 = 11
7 – 4 = 3When we include or subtract two odd numbers, the result is constantly an even number.For example,7 + 3 = 10
7 – 3 = 4When us multiply two also numbers, the an outcome is always an even number. For example,6 × 4 = 24When we multiply an even number and also an weird number, the an outcome is always an also number. For example,7 × 4 = 28When us multiply two odd numbers, the result is constantly an odd number. For example,7 × 3 = 21
Generalization of Odd and Even Numbers
We deserve to generalize the even and also odd numbers together well. Because that example, if ‘n’ is an even number, then the following odd number is ‘n + 1’, and the next even number is ‘n + 2’, and also so on. Similarly, if ‘n’ is an odd number, climate the next also number is ‘n + 1’, and the following odd number is ‘n + 2’, and so on.

For example, if we want to write a series of five odd numbers starting from 73, we can write the as:
73, 73 + 2, 73 + 4, 73 + 6, 73 + 7
73, 75, 77, 79, 81
