Question

let n represent any integer.write an expression for the sum of that number and the next three even integers after it.simplify your expression fully

Answer 1

Sum means addition. Since we're doing even integers, you add 2, not 1. Basically, it's saying a number plus that number plus two... For example, 1 + 2 + 4 + 6. See? You'd get n + (n+2) + (n+4) + (n+6). Now combine like terms. 4n+12 is your answer.
