middle brother's age:21
(x-1) + x + (x+1) =63 3x=63 x=21
The sum of three consecutive integers is -72
I think the answer is zero. The only 15 consecutive integers whose average is 7 are the integers 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14. For any odd number of consecutive integers the average will be equal to the middle number, and this is the only group of 15 consecutive integers with 7 as the middle number. The product of any group of numbers that includes 0 will always be 0 because 0 times anything is 0.
Your question is not well formed, but i assume you mean 3 consecutive integers that sum to -363. If that is the case solve the following equation: (n-1) + (n) + (n+1) = -363 to give you the middle integer.
21, 23, 25. Reasoning: Call the unknown middle member of the three consecutive integers m. Then m - 2 + m + m+2 =69; 3m = 69; m = 23.
9, 11, 13, 15 The solution equation is A + B = 24 where B = A +2 (the consecutive odd integer) 2A +2 = 24 A = 11, B = 13
There are three consecutive integers. Let's call the middle one x. The one before it is x - 1 and the one after it is x + 1. Adding them together equals 3x. That means that whatever they equal has to be a multiple of 3. Since 176 is not divisible by 3, you will not be able to find three consecutive integers with that total.
Suppose the middle integer is a. Then the three consecutive integers are a-1, a and a+1. Now, 3*a = (a-1)+(a+1) + 1 So 3a = 2a + 1 => a=1 So the three numbers are 0, 1 and 2
9,11,13
Middle integer must be a third of 93 so integers are 30, 31 and 32.
153/3 = 51The middle number is 51, so the numbers are...50, 51 and 52
To do these problems the algebra way, make n the middle integer and call the 3 integers n-1, n, and n+1.(n-1) + n + (n+1) = -93simplifying the left side,3n = -93divide both sides by 3 to get n by itself ('isolate' n)n = -31So the 3 consecutive integers are -32, -31, and -30.-32, -31, -30
The Jonas brothers are three brothers who have a band together called the Jonas brothers the oldest brother is Kevin the middle brother is joe and the youngest us nick. Thery r amazing singers and they are all REALLY cute!!!!!!
