Difficulty: Easy
Correct Answer: 100
Explanation:
Introduction / Context:
Alternating multipliers (e.g., *2, *4, *2, *4, …) generate many exam sequences. Here we will test whether such a pattern holds and isolate the single inconsistent value.
Given Data / Assumptions:
Concept / Approach:
Try the pattern “multiply by 2, then multiply by 4,” repeating. Check each step consecutively.
Step-by-Step Solution:
6 → 12: *2 ✔12 → 48: *4 ✔48 → 100: should be *2 = 96, but the term is 100 ✖From 48 (corrected to 96), the pattern continues: 96 → 384 (*4) ✔384 → 768: *2 ✔; 768 → 3072: *4 ✔
Verification / Alternative check:
Using 96 instead of 100 restores the exact alternating *2, *4 pattern across the entire sequence.
Why Other Options Are Wrong:
Common Pitfalls:
Ignoring simple alternation. Always check for repeating multipliers before trying more complex transforms.
Final Answer:
100
