#number series

Aptitude and Reasoning

Identify from the options given below the unwritten number (?) in the series: 360, ?, 180, 60, 15, 3

In aptitude and reasoning, quantitative reasoning dictates that ratio, percentage and series logic determine correct calculation. Therefore 360 is correct as it meets mathematical and logical criteria, supported by mechanistic studies and conserved across related systems.

Ref: Agrawal, Quantitative Aptitude for Competitive Examinations, Chapter 5, Logical Reasoning and Probability, covers ratios, percentages, series completion, time-distance and analytical reasoning explaining problem-solving strategies for competitive assessments.
