Friends, here's a nice maths trick usually called ANGEL NUMBER 421( the smallest prime formed by two powers in logical order from right to left ). In this trick, while doing calculations we'll get 4 2 1 at the last and will continue to get that only.

1) Select any whole number.

2) If it is an even number, divide it by 2 ; if it is odd number, multiply it by 3 and then add 1.

3) Repeat the steps followed in step 2 until you get the loop value 4,2,1 in repitition.

For an instance, let's take the whole number 20

Since 20 is an even number, so 20/2 = 10

10 is an even number, so 10/2 = 5

5 is an odd number, so 5*3+1 = 16

16 is an even number, so 16/2 = 8

8 is an even number, so 8/2 = 4

4 is an even number , so 4/2 = 2

2 is an even number, so 2/2= 1

1 is an odd number, so 1*3+1 = 4

4 is an even number, so 4/2 = 2

2 is an even number, so 2/2 = 1

.

And going further, we'll continuously get 4, 2, 1 in repitition.......
