What is the odd numbers of 21?

The odd numbers from 1 to 100 are: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, 59, 61, 63, 65, 67, 69, 71, 73, 75, 77, 79, 81, 83, 85, 87, 89, 91, 93, 95, 97, 99.

What is the sum of first 21 consecutive odd numbers?

For example, if we put n = 21, then we have 21 x 21 = 441, which is equal to the sum of the first 21 odd numbers.

Can you add 3 odd numbers to get 30?

It is not possible because according to rule of mathematics sum of two odd numbers is always even, take any example. 3+5=8. 7+13=20 etc and then sum of one odd and one even number is always odd number hence in no combination odd and even can turn up to be even which is 30.

What are three consecutive odd integers have a sum of 27?

The three consecutive odd numbers whose sum is 27 are 7, 9 and 11.

Is 21 a composite number?

Yes, since 21 has more than two factors i.e. 1, 3, 7, 21. In other words, 21 is a composite number because 21 has more than 2 factors.

Is 21 an even number?

21 is not an even number.

What are three consecutive odd integers with a sum of 123?

1 Answer

• Odd integers that are consecutive are 2 apart.
• So if the smallest odd integer is called n , then the next two odd integers are n+2 and n+4 .
• We want the sum to be 123 , so.
• n+(n+2)+(n+4)=123.
• 3n+6=123.
• 3n=117.
• n=39.
• So the three consecutive odd numbers are: 39,41,43.

What are three consecutive numbers with a sum of 117?

So your answer is 37, 39 and 41.

What is the sum of three consecutive odd numbers?

The sum of three consecutive odd numbers is 21. Find the numbers. Let one number be x. Then, the other number will be x+2. It is given that their sum is 21. x+4 = 9. Was this answer helpful?

How do you find three consecutive integers whose sum is 21?

Here we will use algebra to find three consecutive integers whose sum is 21. We assign X to the first integer. Since they are consecutive, it means that the 2nd number will be X+1 and the third number will be X+2 and they should all add up to 21.

What are the two numbers that should all add up to 21?

Since they are consecutive, it means that the 2nd number will be X + 1 and the 3rd number will be X + 2 and they should all add up to 21. Therefore, you can write the equation as follows: To solve for X, you first add the integers together and the X variables together. Then you subtract three from each side, followed by dividing by 3 on each side.
