Question

Find the average of each of the following

1. The first 5 odd numbers____

2. The first 5 even numbers____

3. All numbers from 1 to 13_____

4. All numbers from 20 to 30_____

5. The first 5 multiples of 4_____

Answer 1

1. The first 5 odd numbers:

The first 5 odd numbers are 1, 3, 5, 7, 9.

Average = (1 + 3 + 5 + 7 + 9) / 5 = 25 / 5 = 5.

2. The first 5 even numbers:

The first 5 even numbers are: 2, 4, 6, 8, 10.

Average = (2 + 4 + 6 + 8 + 10) / 5 = 30 / 5 = 6.

3. All numbers from 1 to 13:

Sum of numbers from 1 to 13 = (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 +13) = 91.

There are 13 numbers in this range.

Average = Sum / Count = 91 / 13 = 7.

4. All numbers from 20 to 30:

Sum of numbers from 20 to 30 = (20 + 21 + 22 + 23 + 24 + 25 + 26 + 27 + 28 + 29 + 30) = 275.

There are 11 numbers in this range.

Average = Sum / Count = 275 / 11= 25.

5. The first 5 multiples of 4:

The first 5 multiples of 4 are: 4, 8, 12, 16, 20.

Average = (4 + 8 + 12 + 16 + 20) / 5 = 60 / 5 = 12.

So, the averages are:

1. Average of the first 5 odd numbers: 5.

2. Average of the first 5 even numbers: 6.

3. Average of the numbers from 1 to 13: 7.

4. Average of the numbers from 20 to 30: 25.

5. Average of the first 5 multiples of 4: 12.
