Patterns In Whole Numbers

Patterns

A sequence of number is a pattern.

We can arrange numbers in shapes consisting of dots.

  • Every number can be arranged as a line.
  • Some numbers like 3, 6 and 10 can be arrange as a triangle.
  • Some numbers like 4, 9 and 16 can be arrange as a square
  • Some numbers like 6, 8 and 10 can be arrange as a rectangle.

Patterns observations:

Observe the pattern carefully

Multiply 3 by 9, 99, 999, 9999.

Solution:  3 x 9 = 3 x (10 – 1) = 27

3 x 99 = 3 x (100 – 1) = 297

3 x 999 = 3 x (1000 – 1) = 2997

3 x 9999 = 3 x (10000 – 1) = 29997

Thus, a patter can be formed for the given numbers following the same rule that is,

3\left( {n + 1 - 1} \right) , where n = 9,99,999………
