The Most Common Mistake: The 5000 TrapIf you got 5000, you’re not alone. This mistake happens because of the way our brains naturally group numbers.
Most people see four 1000s in the sequence and instinctively think:
1000 × 4 = 4000
Then, they quickly add the smaller numbers:
4000 + 40 + 30 + 20 + 10 = 5000 (which is incorrect!)
But the problem isn’t structured that way. Let’s go step by step and solve it correctly.
Step-by-Step Breakdown: Finding the Correct AnswerLet’s carefully add each number to ensure accuracy.
Step 1: Start with 10001000
Step 2: Add 401000 + 40 = 1040
Step 3: Add another 10001040 + 1000 = 2040
Step 4: Add 302040 + 30 = 2070
Step 5: Add another 10002070 + 1000 = 3070
Step 6: Add 203070 + 20 = 3090
Step 7: Add another 10003090 + 1000 = 4090
Step 8: Add 104090 + 10 = 4100
Final Answer: 4100
