What is the average of first 10 odd whole numbers?
The average is 10. You will find that the average when adding together the first n odd numbers is always equal to n.
The sum of two consecutive odd numbers is 44?
Let's call the first odd number x. Since the numbers are consecutive, the second odd number would be x + 2. The sum of the two numbers is 44, so the equation would be x + (x + 2) = 44. Solving this equation yields x = 21, which means the two consecutive odd numbers are 21 and 23.
The sum of the first n odd whole numbers is equal to?
900
How do you figure out the sum of the first 25 odd numbers without doing 1 3 5 and so on?
The sum of the first n odd numbers is n squared. 25 x 25 = 625
Is the sum of two even numbers even or odd?
The sum of two even numbers is always EVENYes.Proof:We can consider an even number as 2*n, and an odd number as 2*n+1.The sum of two even numbers would be 2*n+2*m=2*(n+m), an even number.
Arithmetical average of the first one million odd numbers?
The answer is one million (the average of the first n odd numbers is always n.)
How many odd numbers are between 38 and?
The number of odd numbers between 38 and n = int[abs(n - 38)/2]
What five consecutive odd numbers total 235?
Let the odd numbers be n-4, n- 2, n, n + 2 , n + 4 Hence summing. (n - 4) + (n - 2) + n + ( n + 2) + (n + 4) = 235 5n = 235 (NB The constants add to zero) n = 235/ 5 n = 47 Hence the other four odd numbers are, 43,45,49,51
What is the formula to find sum of n odd numbers?
The set of odd numbers is an arithmetic sequence. Let say that the sequence has n odd numbers where the first term is a1 and the last one is n. The formula to find the sum on nth terms for an arithmetic sequence is: Sn = (n/2)(a1 + an) or Sn = (n/2)[2a1 + (n - 1)d] where d is the common difference that for odd numbers is 2. Sn = (n/2)(2a1 + 2n - 2)
What is the average of first 10 odd whole numbers?
The average is 10. You will find that the average when adding together the first n odd numbers is always equal to n.
The sum of two consecutive odd numbers is the square of the product of the first and fourth prime numbers what are the two odd numbers?
Let n = smallest of the odd numbers, then let n+2 = the larger of the two numbers (Remember, 1 is not a prime number.) n+ n+2 = {(2)(7)}2 2n +2 = 142 2n = 196 -2 2n = 194 n = 97 n + 2 = 99
The sum of two consecutive odd numbers is 44?
Let's call the first odd number x. Since the numbers are consecutive, the second odd number would be x + 2. The sum of the two numbers is 44, so the equation would be x + (x + 2) = 44. Solving this equation yields x = 21, which means the two consecutive odd numbers are 21 and 23.
What is the six greatest odd number?
There is no such number. Given any odd number, n, the number (n + 2) is a greater odd number. You can go on, for ever, finding larger odd numbers.
How many odd numbers are in the 100th row of Pascals triangle?
The number of odd numbers in the Nth row of Pascal's triangle is equal to 2^n, where n is the number of 1's in the binary form of the N. In this case, 100 in binary is 1100100, so there are 8 odd numbers in the 100th row of Pascal's triangle.
What three consecutive odd numbers that have the sum of 339?
Let 'n' be the first odd number,. Then n+ 2 & n + 4 are the second and third odd number. Hence n + (n+2) + ( n + 4) = 339 Add 3n + 6 = 339 3n = 333 n = 111 n + 2 = 113 n + 4 = 115 Hence the three odd consecutive numbers are 111,113 & 115.
The sum of three consecutive odd numbers is 99 what are the numbers?
let the number be n-1, n, n+1 then 3n=99 and so n=33 the numbers are 32, 33, 34
The sum of the first n odd whole numbers is equal to?
900
