Number Series Pattern Analysis
The problem presents a sequence of numbers: 13, 17, 25, 41, 73, ?. The goal is to identify the pattern governing this sequence and determine the number that should replace the question mark.
Step-by-Step Solution
-
Analyze the Differences: First, let's find the difference between consecutive terms in the given series.
- $17 - 13 = 4$
- $25 - 17 = 8$
- $41 - 25 = 16$
- $73 - 41 = 32$
-
Identify the Pattern in Differences: Observe the sequence of differences: 4, 8, 16, 32. We can see a clear pattern here: each difference is double the previous difference.
- $4 \times 2 = 8$
- $8 \times 2 = 16$
- $16 \times 2 = 32$
- Calculate the Next Difference: Following the established pattern, the next difference should be $32 \times 2$. $32 \times 2 = 64$
- Determine the Missing Number: To find the next number in the original series, add this next difference (64) to the last known term (73). $73 + 64 = 137$
Therefore, the number that will be present in place of the question mark is 137.
Conclusion
The number series follows a pattern where the difference between consecutive terms doubles each time. Starting with a difference of 4, the subsequent differences are 8, 16, and 32. The next difference is 64, leading to the final term being 137.
