Perform the following tasks:
simplify the ratio 4 : 22 : 30
complete the pattern: {486, 162, 54, 18, }

1. Simplify the ratio 4 : 22 : 30

Dividing by 2;

2 : 11 : 15

2. Complete the pattern: {486, 162, 54, 18, ___}

We can solve this easily by starting from 18.

First lets check the relation between 18 and 54. Its

We have found a relation between the two numbers. Lets check if this works for another numbers.

So, we can say that the series is decreasing by 3 times.

So, the missing number will be : 6

{486, 162, 54, 18, 6}
