The first three odd numbers are 1, 3, and 5. Their sum is 1 + 3 + 5 = 9.
The numbers are 5, 7 and 9.
1 + 3 + 5 = 9
The sum of the first nine odd numbers is 81.
The numbers are -13, -11, and -9.
The first three odd numbers are 1, 3, and 5. Their sum is 1 + 3 + 5 = 9.
The numbers are 5, 7 and 9.
the sum of the first three numbers is 1 + 3+5= 9
5*9= 45
They are 9, 11 and 13.
1 + 3 + 5 = 9
The sum of the first nine odd numbers is 81.
The sum of 9 odd numbers must be odd and so cannot be an number.
The numbers are -13, -11, and -9.
Well, isn't that a happy little math problem! Let's see, we can choose the odd numbers 1, 7, and 12 to make 20. Remember, there are many ways to approach a problem, so feel free to explore different combinations and see what works best for you. Just remember, there are no mistakes in math, just happy little accidents!
You cannot. The sum of 9 odd numbers must be odd.
9801 * The sum of the first two odd numbers (1+3) is 4, or 22 * The sum of the first three odd numbers (1+3+5) is 9, or 32 * The sum of the first four odd numbers (1+3+5+7) is 16, or 42 * ...and so on So the sum of the first 99 odd numbers, using the pattern above, would be 992 or 9801.
