What is the sum of the first odd positive integers?
The first odd positive integers are "1" and "3" which the sum is 4.
What is the sum of the first three odd numbers?
The first three odd numbers are 1, 3, and 5. Their sum is 1 + 3 + 5 = 9.
Sum first 99 odd numbers?
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.
Sum of the first n odd integers?
Let's talk this out and see if we can work it out. The sum of the first N odd integers means, 1+3+5+7+9+11+... Where N is how many odd numbers we're adding. Let's choose numbers for N, and see if we can find a pattern. N=1 --> 1 (sum of the first odd integer) N=2 --> 1 + 3 = 4 (sum of the first 2 odd integers) N=3 --> 1 + 3 + 5 = 9 (sum of the first 3 odd integers) N=4 --> 1 + 3 + 5 + 7 = 16 Do you notice a pattern yet? Take a look at when N = 2, what is the sum? That's right, 4! and when N = 3... the sum is 9. N = 4 the sum is 16.... I see a pattern, do you? Answer: If you don't, you'll notice that the sum of the first N odd integers is always = N2
Will the sum of 3 odd numbers be even?
No, the sum of three odd numbers will always be odd.
What is the sum of the first 2000 consecutive odd numbers?
Answer is 4000000: The sum of the first N odd numbers is N^2. Look at 1,3,5 for example. There are 3 numbers and the sum is 9 which is 3^2. Add 7 and the sum is 16 which is 4^2. So the of the first 2000 consecutive odd numbers is 2000^2 Note 2000 is 2(10^3). When we square that it is 4x10^6=4000000
What 3 odd prime numbers have sum 32?
That isn't possible. The sum of three odd numbers will always be odd. You can make the sum of 3 prime numbers equal to 32 if one of them is 2 (which is not odd).
How do you figure out the sum of the first 25 odd numbers without doing 1 3 5 and so on?
The sum of the first n odd numbers is n squared. 25 x 25 = 625
What are the first three odd numbers?
the sum of the first three numbers is 1 + 3+5= 9
What is the sum of the first 1500 consecutive odd numbers?
You can work this out by realizing that the sum of the first x odd numbers is equal to x2.Consider the following examples:The first three odd numbers: 1 + 3 + 5 = 9The first five odd numbers: 1 + 3 + 5 + 7 + 9 = 25The first ten odd numbers: 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 = 100In each case, the number of odds you're adding together is the square root of their sum. This means that the first 1500 consecutive odd numbers have a sum of 15002, which equals 2250000, or two and a quarter million.
What is the sum of the first 430 odd numbers?
1 + 3 + 5 + ... + 857 + 859 = 184900
The sum of 3 odd numbers is odd-true or false?
