Difficulty: Easy
Correct Answer: 6 2
Explanation:
Introduction / Context:A straightforward arithmetic progression with a fixed negative step size challenges you to maintain accuracy over multiple decrements.
Given Data / Assumptions:
Concept / Approach:Check consecutive differences to confirm the common difference, then continue the pattern by the same subtraction.
Step-by-Step Solution:
30 − 34 = −4; 26 − 30 = −4; 22 − 26 = −4; …After 10, next terms are 10 − 4 = 6 and 6 − 4 = 2.Verification / Alternative check:Writing the tail: 18, 14, 10, 6, 2 confirms a constant −4 cadence.
Why Other Options Are Wrong:
Common Pitfalls:Skipping a step when counting down by fours.
