Double the mean.
e.g. 7 and 8 7+8=15
15/2=7.5
mean of 7 and 8=7.5
Alternatively you could just add 1/2 and multiply by two. ( it is the same method just worded slightly simpler.
7 8
The numbers are 54 and 56.
Let the three consecutive whole numbers be ( x ), ( x + 1 ), and ( x + 2 ). Their sum can be expressed as ( x + (x + 1) + (x + 2) = 3x + 3 ). Setting this equal to 1539 gives the equation ( 3x + 3 = 1539 ). Solving for ( x ) results in ( x = 512 ), so the three consecutive whole numbers are 512, 513, and 514.
5+2+1=8 and 8 is not divisible by 3.
The numbers are 22 and 24.
There are none.
The three consecutive whole numbers you are looking for are 1, 2, and 3. The sum of the first two numbers, 1 + 2 = 3.
No
4,5
49 + 50 = 99
7 8
The numbers are 54 and 56.
Let the three consecutive whole numbers be ( x ), ( x + 1 ), and ( x + 2 ). Their sum can be expressed as ( x + (x + 1) + (x + 2) = 3x + 3 ). Setting this equal to 1539 gives the equation ( 3x + 3 = 1539 ). Solving for ( x ) results in ( x = 512 ), so the three consecutive whole numbers are 512, 513, and 514.
Consecutive whole numbers have no other whole numbers between them.
5+2+1=8 and 8 is not divisible by 3.
No, the sum of two consecutive numbers is always an odd number, and is not divisible by two.
The numbers are 22 and 24.
