Seventy-six and Seventy-eight, or 76+78 = 154
Let the middle number of the three be n. Then the three consecutive numbers are n-1, n, n+1. Their sum is n-1 + n + n+1 = 3n Their average is 3n / 3 = n The difference between their sum and their average is 3n-n = 2n 2n = 156 => n = 78. Thus the three numbers are 77, 78, 79
Let's denote the two consecutive numbers as x and x+1. The product of two consecutive numbers is given by x(x+1). We are given that x(x+1) = 6162. By solving this equation, we find that x = 78. Therefore, the two consecutive numbers are 78 and 79, as 78 * 79 = 6162.
How about: 11+67 = 78
The three integers are -27, -26 and -25.
26.
The numbers are 78 and 79.
Half of 154 is 77, so your numbers are 76 and 78.
The easiest way to solve this problem is to look at the sets of numbers beginning with each of the numbers given. Choice A begins with the number 24, so add the three consecutive even numbers beginning with 24, that is, 24 + 26 + 28. The sum of these numbers is 78, so the answer is choice A: 24.
78+79+80=237
The three numbers added together will equal 228. The average of the three numbers will be 228 / 3 = 76. If you take one even integer from either side of 76, you get 74 and 78.Therefore, the three consecutive even integers which equal 228 are 74, 76 and 78.
Seventy-six and Seventy-eight, or 76+78 = 154
Let the middle number of the three be n. Then the three consecutive numbers are n-1, n, n+1. Their sum is n-1 + n + n+1 = 3n Their average is 3n / 3 = n The difference between their sum and their average is 3n-n = 2n 2n = 156 => n = 78. Thus the three numbers are 77, 78, 79
25, 26 and 27
231 / 3 = 77So 76 + 77 +78 = 23177
Consecutive integers mean the numbers follow one after the other. So, if you let x be an integer, then x, x+1, and x+2 are your three consecutive integers. "Sum" means they were added. So: x+(x+1)+(x+2)=237 => 3x+3 = 237 => 3x = 234 => x=78. Therefore, your integers are: 78, 79, and 80.
Divide the sum of the two consecutive odd integers by 2: 156/2=78. The two consecutive odd integers will be one more and one less than 78, so the smaller will be 77 and the larger will be 79.
