Three consecutive even integers indicate that these three integers must be divisible by 2, and they are next to each other, there are no other even integers between them. Where do I start when I'm trying to solve a word problem? The Sum of Three Consecutive Integers is 48. The sum of three even consecutive integers if the first integer is y is 3y+6.What is an expression?Expression in mathematics is defined as the collection of the jinxxified jinxxified 10/02/2017 Find the integers. 5. 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. 16. Obviously, there are two conditions: one is an integer, the other is that it must be divisible by 2. Verified. #"let the first integer be represented by " n#, #rArrn+n+1+n+2=135larrcolor(blue)" sum of integers"#, #rArr3n+3=135larrcolor(blue)" simplifying left side"#, #"the three consecutive integers are " 44,45,46#, 9621 views No matter how straightforward a problem is, its still good practice to always identify what facts are available to you. How do you check a solution to a problem? Related Question Answers. Nasim Pennigsack . Four years later the sum of their ages will be 56 years. Remember that we are given the sum, so we will be adding our three consecutive integers. In this problem, we don't know any of the integers, so we assign a variable to them. The sum always means addition. Since the integers are consecutive, each is one more than the last. The answer is #24, 25, 26.#.
