- Formula Used: Average = (Sum of Values/Number of Values)
- Calculation: As, an average of 7 consecutive even numbers is 12. Sum of the 7 consecutive even numbers = 12 × 7 = 84.
- ∴ The smallest number is 6. Download Soln PDF. Share on Whatsapp.
How do you find the average of 5 consecutive odd numbers?
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.
What are two consecutive odd numbers?
If x is any odd number, then x and x + 2 are consecutive odd numbers. E.g. 7 and 9 are consecutive odd numbers, as are 31 and 33.
What is the average of odd numbers upto 999?

How do you find two consecutive positive odd integers whose product is 63?
2 Answers By Expert Tutors I can answer this based on knowledge of composite numbers: 7 times 9 = 63. The only other pair of numbers satisfying this is -7 and -9. There are your two pairs, {7,9} and {-7,-9}, the same as in Kenneth’s answer.
What is the average of 5 consecutive odd numbers?
So average is (5a+20)/5= a+4 which is same is c. Since the difference between each consecutive odd numbers is 2, The average would be given as : So the avg of 5 consecutive odd numbers is the middle term, which in this case is ‘c’.
How do you find the average of a series of numbers?
Average= a+6=d. Going further, if such a series is given with same difference,the average always happens to be the middle term,as simple as that. The average of any even no: of consecutive even numbers is odd number between them. avg =2+4/2 =3.
What is the average of the first three numbers?
The average of six numbers is 32. If each of first three numbers is increased by 2 and each of the remaining three numbers is decreased by 4, then the new average is : 5). The average of the three numbers x, y and z is 45. x is greater than the average of y and z by 9. The average of y and z is greater than y by 2.
Why is the average of first 10 times the first 24?
As the average is 20 means 11th one 20 and plus minus the effect of other. Since average of first 10 is 24 means they are giving +4 for other number so average is 20, it will decrease other number value. Thats why -10*4.
