Background
Topic: Translating verbal statements into algebraic expressions and simplifying.
This question tests your ability to represent a sequence of consecutive even integers algebraically, then combine and simplify the resulting expression.
Key Terms and Formulas
Consecutive even integers: Numbers that differ by 2 (e.g., 2, 4, 6, 8).
Algebraic expression: A mathematical phrase involving variables and operations.
For four consecutive even integers starting with , the sequence is:
(first integer)
(second integer)
(third integer)
(fourth integer)
