How do you find the average of four consecutive odd numbers?
How do you find the average of four consecutive odd numbers?
- Given: Average of four consecutive odd numbers = 104.
- Formula: Average = (Sum of terms)/(Number of terms)
- Calculation: Let P, Q, R and S be a, (a + 2), (a + 4) and (a + 6) respectively.
- ∴ The sum of P and S is 208.
- Alternate Method. If the average of given numbers is x, then the sum of the first and last numbers is 2x.
What is the average of odd number?
The sum of the first n terms of an arithmetic sequence when the nth term is known is: Sn = (n/2) × [a + L]. The average is given by the formula: Average = sum of the observations/number of observations. Average = sum of odd numbers up to 100 / 100 = 5000/100 = 50.
What is the consecutive odd numbers?
Consecutive odd integers are odd integers that follow each other by the difference of 2. If x is an odd integer, then x + 2, x + 4, x + 6 and x + 8 are consecutive odd integers.
What is the average of A B C and D?
A, B, C and D are four consecutive odd numbers and their average is 42. What is the product of B and D?…
1890 C.1845…
What is the last / largest of the 6 consecutive odd numbers?
Since the numbers are odd, I will take the first number of the 6 consecutive odd numbers as (n+1). So the first number in the series of the 6 consecutive odd number is (n+1) = 14+1 = 15 and the last / largest of the number is (14+11) = 25.
How many consecutive odd numbers are there in 146?
A, B, C, D and E are 5 consecutive odd numbers. If the total of A and C is 146, then how do you find the value of E? also the numbers A, B, C, D, E all are odd and consecutive, so they can be something like: A, A+2, A+4, A+6, A+8 because they are odd consecutive, so we also have:
What is the product of B and D=41 and C?
=x+ 3 = 42 …… (taking 4 common from both the sides and cancelling each other) B*D= 41*45 = 1845. Hence the answer is 1845. Since avg. Is 42…. it surely lies between B and C. So clearly B=41 and C=43. As the numbers are consecutive, so the four numbers are 39,41,43 and 45. Product of B and D= 41×45=1845. Let 4 consecutive odd no.
