Numbers Involved: 15, 25, and 35
Quick Calculation: This pattern is circular. Group the same numbers and multiply by the
number of times they appear.
Solution
Step 1: Identify the numbers involved
Numbers involved: 15, 25, and 35.
Step 2: Count the number of times each number appears
15 appears 15 times.
25 appears 16 times.
35 appears 13 times.
Step 3: Multiply the numbers by the number of times they appear
15 × 15 = 225
25 × 16 = 400
35 × 13 = 455
Step 4: Add the results
225 + 400 + 455 = 1080
Final Answer: The total sum for Pattern e is 1080
