Using the following pattern determine the number in the 4th place:

9, 12, 18, .....

9,12,18,24

30

To determine the number in the 4th place, we need to identify the pattern in the given sequence: 9, 12, 18, ...

Looking at the sequence, we can observe that each number is obtained by multiplying the previous number by a specific factor. In this case, it seems like each number is obtained by multiplying the previous number by 1.5.

To find the number in the 4th place, let's continue the pattern:

9 * 1.5 = 13.5 (not in the sequence)
13.5 * 1.5 = 20.25 (not in the sequence)
20.25 * 1.5 = 30.375 (not in the sequence)
30.375 * 1.5 = 45.5625

Therefore, the number in the 4th place is approximately 45.5625.
