1 and 13 works, since 1 + 13 = 14. Also 7 and 7, since 7 + 7 = 14. There are other combinations which add up to 14.

When two numbers are added together, the result is called a sum. The two numbers being added together are called addends.

1 Expert Answer So, if negative and fractional numbers are acceptable, the answer is yes!

But, there are only two single-digit numbers that add up to 15: 6 and 9, 7 and 8. The possible number whose combination would result in sum of 15 are: 69, 78, 87, 96.

11 + 1 + 1 + 1 = 14.

Even and Odd Numbers. Even numbers can be divided evenly into groups of two. Odd numbers always end with a digit of 1, 3, 5, 7, or 9. 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31 are odd numbers.

The first first five odd natural numbers are as follows :

• 1,3,5,7 and 9.
• (1+3+5+7+9)/5.
• =25/5.
• =5.
• Therefore, mean=5.

Hence product of first three odd numbers is 15.

Then, the fourth number is 7 (because 6 is even) and the fifth number is 9 (because 8 is even). ∴ the mean of the first five odd natural numbers is 5.

Input parameters & values: The number series 1, 3, 5, 7, 9. Therefore, 25 is the sum of first 5 odd numbers.

Answer. The average is 25.

Answer: The mean of the first 10 odd numbers is 10.

Now, we will divide this by 10 as there are a total 10 numbers. Hence, the arithmetic mean of first ten odd natural numbers is 10.

Hence, all numbers other than 2 are odd prime. So, the first 10 odd prime numbers are as follows 3, 5, 7, 11, 13,17, 19, 23, 29, 31. In a list of even numbers arranged in order. So, here in the list (3, 5, 7, 11, 13,17, 19, 23, 29, 31).

Odd numbers are 1, 3, 5, 7, 9, 11, 13, 14…… The Smallest two digit even number 10 and Smallest two digit Odd number 11.
