Math Problem Statement
Explain step 4
Solution
To explain Step 4 in the image you uploaded, let’s analyze the patterns leading up to it:
Key Observations Before Step 4:
- Input row: Contains sets of 4-digit numbers (e.g., 1234, 5678, etc.).
- Step 1: Converts each 4-digit input into a two-digit number.
- Step 2: Maps these numbers to pairs of letters (JJ, ZZ, etc.).
- Step 3: Transforms these letter pairs into 4-digit numbers.
Step 4 (Explanation):
In Step 4, the values from Step 3 are reduced to two-digit numbers again. Each of these new numbers seems to be derived by summing the individual digits of the 4-digit numbers from Step 3. Here’s how this works:
-
1224 (from Step 3):
- Sum of digits:
- Result = 25.
-
5652 (from Step 3):
- Sum of digits: .
- Result = 90.
-
2331 (from Step 3):
- Sum of digits: .
- Result = 23.
-
6759 (from Step 3):
- Sum of digits: .
- Result = 191.
-
3438 (from Step 3):
- Sum of digits: .
- Result = 98.
Thus, in Step 4, each 4-digit number is broken down into its individual digits, summed, and multiplied by a factor to create the final two-digit value shown in that step.
Would you like a deeper analysis or have more questions on the following steps?
Here are 5 related questions:
- How are the two-digit numbers in Step 1 calculated from the input?
- What is the method used to convert numbers to letters in Step 2?
- What pattern connects Step 2 (letters) and Step 3 (numbers)?
- Why are the sums from Step 4 multiplied by certain factors?
- How does the sequence change in Step 5 with the appearance of letters?
Tip: Always look for consistent transformations when dealing with step-by-step processes. Each step likely follows a pattern that can be identified through careful observation.
