Patterns in Numbers and Alphabets

In the previous chapter, we have already studied patterns in shapes. Not only shapes but patterns are also seen involving numbers and alphabets.

Patterns in Numbers

A number pattern is a list of numbers. This pattern generally follows a common relation between the list of the numbers.

There are two types of number patterns.

  • Increasing Number Pattern
  • Decreasing Number Pattern

Increasing Number Pattern

If the numbers in the pattern are increasing by a particular order, then it is said to be in increasing number pattern.

Example:

Let us discuss with an example. In the below pattern, we have to guess the next number.

G2_1_Inc Pattern

Observing the pattern carefully one can see that, the difference between two adjacent numbers is 2 and the numbers are increasing by 2.

G2_2_Inc Pattern

So, the next number will be 10 + 2 = 12.

Hence the complete pattern is

G2_3_Inc Pattern

Decreasing Number Pattern

If the numbers in the pattern are are decreasing by a particular order, then it is said to be in decreasing number pattern.

Example:

Let us discuss with an example. In the below pattern, we have to guess the next number.

G2_4_Dec Pattern

Observing the pattern carefully one can see that, the difference between two adjacent numbers is 2 and the numbers are decreasing by 2.

G2_5_Dec Pattern

So, the next number will be 33 – 2 = 31.

Hence the complete pattern is

G2_6_Dec Pattern

Patterns in Alphabets

A letter pattern is a list of letters or English alphabets. This pattern generally follows a common relationship between all the letters.

Here it is explained with an example.

Example:

Find the next letter of the given pattern.

A, D, G, J, M, P, ?

Answer:

A, D, G, J, M, P

In the above sequence, the letters are written after skipping two of the letters between them.

G2_7_Alp pattern

So, the next letter will be

G2_8_Alp Pattern

Hence the complete pattern is

A, D, G, J, M, P, S.

Many more patterns can be seen with the help of the 26 alphabets.
