What is the average of the first 7 odd integers?
First 7 odd natural numbers are: 1, 3, 5, 7, 9, 11 and 13. The mean of the first 7 odd natural numbers is 7.
What is the sum of first 13 consecutive odd numbers?
Hence the sum of 13 consecutive odd natural numbers is 169.
How much is the sum of first 7 consecutive odd numbers?
As we know, the odd numbers are the numbers which are not divisible by 2. They are 1,3,5,7,9,11,13,15,17,19 and so on….Sum of Odd Numbers.
| Number of consecutive odd numbers (n) | Sum of odd numbers (Sn) |
|---|---|
| 6 | 62=36 |
| 7 | 72=49 |
| 8 | 82 = 64 |
| 9 | 92 = 81 |
What is the average of first 7 even numbers?
Given data is 2, 4, 6, 8, 10, 12, 14. =2+4+6+8+10+12+147=567=8.
What is mean of the first 7 odd numbers?
Solution: First 7 odd natural numbers: 1,3,5,7,9,11,13. Formula of mean : So, mean of First 7 odd natural numbers: Hence the mean of first 7 odd natural numbers is 7.
What are the first 13 odd numbers?
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.
How do you express 169 as the sum of 13 odd numbers?
Express 169 as the sum of 13 consecutive odd natural numbers.
- Sum of first odd numbers.
- = 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 + 21 + 23 + 25.
- = (1 + 25) + (3 + 23) + (5 + 21) + (7 + 19) + (9 + 17) + (11 + 15) +13.
- = 26 + 26 + 26 + 26 + 26 + 26 + 13.
- = (6 x 26) + 13.
- = 156 + 13.
- = 169.
What is the average of first 5 consecutive odd numbers?
61
Now it is given that the average of five consecutive odd numbers is 61. Now as we know that the average is calculated as the sum of numbers divided by the total numbers. So the first odd number which is the smallest odd number is 57. And the highest odd number which is the fifth odd number = (x + 8) = 57 + 8 = 65.
How do you find the average of a series of numbers?
For a short series of consecutive numbers, it is easy to find the average by finding the middle number in the sequence, or the median. For longer series of numbers, there are formulas you can use to quickly calculate the average, as long as you know what the first term and last term in the series are. Count the number of terms in the series.
What is the average of five consecutive odd numbers?
The average of any five consecutive odd numbers is the third number of the sequence (in this case, c). You can prove this by setting a equal to c-4, b = c-2, d= c+2, and e= c+4. Add those four numbers together with c, and the sum of the five numbers is 5c. Divide that sum by 5 to get the average of the five numbers, which is c.
What is the middle number in a series?
This is the number that has the same amount of terms on either side of it. This middle number will be the average of the series. For example, in the sequence 3, 4, 5, 6, 7, 8, 9, the middle number is 6. It has three numbers to the left of it, and three numbers to the right of it.
What is the lowest number in this set of odd numbers?
The average (62 in this case) of an odd number of consecutive numbers is the middle number of the set. That means this set begins at four even numbers below 62 and ends at four even numbers above 62. Therefore, the lowest number in this set is 54.
