You can put this solution on YOUR website! What is the sum of the first 5000 odd numbers?
Step 1. So we need to add the first 5000 odd numbers from 1-9999.
Step 2. We note that 1+9999=10,0000 and 3+9997=10,000 5+9995=10,000 and so on.
Step 3. So we will have 2500 pairs of these numbers adding to 10,000.
Step 4. Then 2500*10000=25000000.
Step 5. ANSWER: The sum of the first 5000 odd numbers is 25 million.
I hope the above steps were helpful.
