Let x = the smallest even integer, x + 2 = the next even integer, and x + 4 = the largest even integer. Write the equation x + x + 2 + x + 4 = –78. Simplify the equation as 3x + 6 = –78. Solve the equation by subtracting 6 and dividing by 3 on both sides of the equation. Check that the sum of the integers –28, –26, and –24 is –78.

Base case: $n=1$. Picking $2n+1$ random numbers 5,6,7 we get $5+6+7=18$. So, $2(1)+1=3$ which indeed does divide 18. The base case holds. Let $n=k>=1$ and let $2k+1$ be true. We want to show $2(k+1)+1$ is true. So, $2(k+1)+1=(2k+2) +1$.... Now I'm stuck. Any ideas?

The key here is that your integers are CONSECUTIVE (one after the other), but also that they are EVEN (meaning that they skip the odd numbers in between, so the difference from one number to the next would be a difference of 2): Let x be the smallest number, y the middle number, and z the largest number: x = x . y = x + 2. z = y + 2

find four consecutive odd integers such that the sum of the first three exceeds the fourth by 18. Let the first of the four consecutive odd integers = F Then others are: F + 2, F + 4, and F + 6 We therefore have: F + F + 2 + F + 4 = F + 6 + 18 3F + 6 = F + 24 3F - F = 24 - 6 2F = 18 F, or first of the three odd integers = , or Other three are:
