What should be come in place of "?" in the given series? 10,19,?,199,7...
Understanding the Series
To identify the missing number in the series: 10, 19, ?, 199, 775, 3079, 12295, we need to analyze the relationship between the numbers.
Analyzing Differences
Let's calculate the differences between consecutive terms:
- From 10 to 19: 19 - 10 = 9
- From 19 to ?: Let’s denote the missing number as x.
- From x to 199: 199 - x
- From 199 to 775: 775 - 199 = 576
- From 775 to 3079: 3079 - 775 = 2304
- From 3079 to 12295: 12295 - 3079 = 9216
Now we have a new series of differences: 9, (199 - x), 576, 2304, 9216.
Identifying Patterns
The differences appear to follow a pattern:
- 9 = 3^2
- 576 = 24^2
- 2304 = 48^2
- 9216 = 96^2
It seems the differences are the squares of multiples of 3.
Finding the Missing Difference
To find the missing difference (199 - x), we notice the pattern of squares doubles:
- The next difference before 576 should be 36 (6^2).
Thus, we set up the equation:
199 - x = 36.
Solving for x gives:
x = 199 - 36 = 163.
Conclusion
The missing number in the series is 163. The complete series is 10, 19, 163, 199, 775, 3079, 12295.
