Let the consecutive numbers be n,n+1, n+2, n+3, & n+ 4.
Add
n + (n+1)+(n+2) + (n + 3) + ( n + 4) = 115
5n + 10 = 115
5n = 105
n = 21
N+1 = 22
n+2 = 23
n+3 = 24
n + 4 = 25
So the five consecutive numbers are 21,22,23,24 & 25.

∙ 2012-04-11 02:29:25You have five numbers that add up to 115. What is the average value of those five numbers? Now, how do you choose five consecutive numbers that have that average value?
The numbers are 21, 22, 23, 24, and 25.
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.
Since 115 ends in five, it will divide by '5'. Hence '5' is one of the factors. 5)115 = 23 Hence '23' is the other factor. Since '23' is a prime number, there are no other factors for 115 , but 5, and 23. except '1' & 115'.
gcf for these numbers 345 253 and 115 is 23.
115 is one hundred and fifteen.
The numbers are 21, 22, 23, 24, and 25.
115 + 116 = 131
113, 114, 115
The numbers are 111, 113 and 115.
114, 115 & 116
21,22,23,24,25---The Algebra Solution MethodFor any 5 consecutive numbers, starting with X, the four following are X+1, X+2, X+3, and X+4.The equation becomes X + (X+1) + (X+2) + (X+3) + (X+4) = 115So 5x + 10 = 115 and X =21---The Arithmetic Mean MethodAny five consecutive numbers will have an average or mean equal to the middle number. Knowing that 5 times that number is 115,5M = 115 and the central number M is 23.
All numbers ending in five are odd.
23*5 = 115 So pick any four numbers: integers, fractions, irrational numbers, whatever. Add them together to give a sum S. Let the 5th number be 115 - S Then: sum of all five numbers = (sum of the first four numbers) + (the fifth number) = S + (115 - S) = 115 And the count of numbers = 5 So mean = Sum/Count = 115/5 = 23
Yes. Five is a factor of all cardinal (whole) numbers ending in five
The first ten consecutive composite positive integers are: 114 115 116 117 118 119 120 121 122 123
Chose any integer x. Three consecutive odd numbers: 2x+1 2x+3 2x+5 2x+5+2(2x+1)=115 2x+5+4x+2=115 6x+7=115 6x=108 x=18 The middle number is 2x+3=2*18+3 = 39
57 and 58.
