Identifying the pattern:
- The given series is: 4.5, 7, 18, ?, 335, 2004
- Let's try to identify the pattern in the series to find the missing number.

Calculating the differences:
- The difference between 4.5 and 7 is 2.5
- The difference between 7 and 18 is 11
- The difference between 18 and the missing number is what we need to find
- The difference between the missing number and 335 is 317
- The difference between 335 and 2004 is 1669

Identifying the pattern:
- Looking at the differences calculated above, we can see that the differences are not following a consistent pattern to derive the missing number directly.
- Let's try another approach to identify the pattern.

Dividing consecutive numbers:
- Divide 7 by 4.5, we get approximately 1.55
- Divide 18 by 7, we get approximately 2.57
- Divide the missing number by 18, we need to find this value
- Divide 335 by the missing number, we need to find this value
- Divide 2004 by 335, we get approximately 5.99

Identifying the pattern:
- By looking at the results of dividing consecutive numbers, we can see an increasing pattern.
- The missing number should be the result of dividing 18 by 7 multiplied by 2.57 to maintain the pattern.

Calculating the missing number:
- (18 / 7) * 2.57 ≈ 6.61
- Multiplying 6.61 by 18 gives us 118.98
Therefore, the missing number in the series is approximately 119.
