The sum of the three consecutive odd integers is 75. The sum of any three consecutive integers is even. The answer will be presented immediately. Identify what we are looking for. Therefore, assuming that the first even integer is represented by 2 * N, then the second and third even integers are 2 * N + 2 and 2 * N + 4. Let x be the odd number. Carmen received. Class 12 Let's have the first integer be #n#. How do you create a linear model in a word problem? In daily life, in addition to being asked to calculate the sum of 3 consecutive integers, you will also encounter finding the sum of 3 consecutive even integers, or finding the sum of 3 consecutive odd integers. #3n = -21# If you can understand this method and are careful in using it you will save a lot of time when these types of puzzles appear. Save my name, email, and website in this browser for the next time I comment. So, we can use 2 * N + 1 to represent the first integer, then the second and third odd integers are 2 * N + 3 and 2 * N + 5. Subject. #n+2 = -5# if there are 48 people in the group, how many are men? Find out the sum of three consecutive integers. Everyone is welcome to use it! What mark does she need on her 5 th test to achieve an average of \( 75 \% \) ?
