Integers are three types of numbers including negative integers, positive integers, and zero. x + \left( {x + 1} \right) + \left( {x + 2} \right) + \left( {x + 3} \right) + \left( {x + 4} \right) + \left( {x + 5} \right) = - \,9. # color(purple)(x = 72/ 3 = 24#, This is the type of puzzle that we should try to perform as mental math (in your head). Verified. Were now ready to write our equation. 3n+3 3 = 135 3. The last condition that we need to satisfy is that the sum of the four consecutive integers must be 238. Enter your email for an invite. Example 2: Find four consecutive integers whose sum is 238. Now that we have the value for the variable n, we can use this to identify the three consecutive integers.
