1. Which of these numbers is not divisible by 2?

Explanation

All the numbers given in the list are divisible by 2 except for the number 5. This is because a number is divisible by 2 if it can be divided evenly by 2 without leaving a remainder. In the case of 5, it cannot be divided evenly by 2 as 5 divided by 2 equals 2 with a remainder of 1. Therefore, 5 is not divisible by 2.

7. What is the name given to numbers divisible by 1 and itself?

Explanation

Prime numbers are a special type of numbers that are only divisible by 1 and itself. They cannot be divided evenly by any other numbers. Decimal numbers, even numbers, and odd numbers do not have this property. Therefore, the correct answer is prime numbers.

Submit

9. What is the formula for the sum of n even numbers? 

Explanation

The formula for the sum of n even numbers is n(n+1). This can be derived by considering that the sum of the first n even numbers is equal to the sum of the first n natural numbers multiplied by 2. The sum of the first n natural numbers is given by the formula n(n+1)/2, and when multiplied by 2, it becomes n(n+1).

Submit
10. What is the formula for the sum of the first n odd numbers?

Explanation

The formula for the sum of the first n odd numbers is n². This can be derived by observing that the first odd number is 1, the second odd number is 3, the third odd number is 5, and so on. It can be noticed that each odd number can be represented as 2k-1, where k is the position of the odd number. By summing up the first n odd numbers using this representation, it can be simplified to n².
