Odd 2. The object of this activity is to find the sum of the first 25 odd counting numbers. One way is to add 1 + 3 + 5...continuing until you have added the first 25 odd numbers. However, this is too much work for the problem. Look for patterns and combinations to find a much easier way to solve this. Apply what you have learned from this problem and find the sum of the first 25 even counting numbers.Now try to work this out... Pump, Pump, Pump... 3.
