 # Odd and Even Mathematical Number Pattern Math formula – Materials and discussions regarding math number pattern included in the discussion of arithmetic in junior high school lessons. On this occasion, the concept of number patterns discussed is about odd number patterns and even number patterns in mathematics. In short, the number pattern can be interpreted as an arrangement of numbers that has regularity in its form, whether it is quantity, or size. You can see a detailed discussion of odd and even number patterns in the two sub-headings below:

## Odd and Even Mathematical Number Pattern

### Odd Number Pattern

Odd numbers are included in the set of natural numbers. An odd number can be defined as an original number which, when divided by 2 and its multiple, is not divisible. Source: Google Images

Find out more about odd numbers through some of the pattern questions below:

#### Example Question 1:

Find the sum of the first 8 odd original numbers!

The sequence of the first 8 odd numbers is 1, 3, 5, 7, 9, 11, 13, and 15. Then n = 8
To find out the sum of all these numbers, we simply need to multiply the sum of the numbers (n) by 2 and the end is 82 = 64

#### Example question 2:

How many numbers are there if the sum of all the numbers is 49?

Because we already know how to calculate the sum of an odd array of numbers is to raise it by 2 or (n2) then from the problem can be drawn an equation:

n2 = 49
n = 49
Then n = 7

### Even number pattern

Even numbers are also a member of natural numbers, their order is: 2, 4, 6, 8, 10, …
To calculate the formula for the nth term on an even number, use the formula >> un = 2n Source: Google Images

To better understand the pattern of even numbers, consider the following description of the addition of even numbers:

The concept of adding 2 consecutive even numbers:
2 + 4 = 10, can be written as 6 = 2 (2+1)

The concept of adding 3 consecutive even numbers:
2 + 4 + 6 = 12, can be written as 12 = 3 (3+1)

The concept of adding 4 consecutive even numbers:
2 + 4 + 6 + 8 = 20, can be written as 20 = 4 (4+1)

From the calculation pattern described above, a conclusion can be drawn where the formula for the sum of the even number patterns is ns = n ( n + 1 )

That’s a simple discussion that I can convey about math number pattern odd and even. Actually there are many other number patterns that exist in mathematics lessons. Maybe in the next articles I will present the discussion for you. ## 1080P HD Spray Dispenser Mini Camera WiFi Aromatherapy Bottle Design Home Security Video Surveillance Video&Audio Recorder ## Mccpuo 4MP Dual Lens E27 Bulb Surveillance Camera WIFI 360 Auto Tracking 360 PTZ IP Camera Color Night Vision IP Security CCTV ## 1080P Wireless Mini IP Camera 4MP Baby Monitor CCTV Indoor Two Way Audio 5G WiFi Security Auto Tracking Mobile Remote Access ## Want to be more intimate with his girlfriend?
