Series and Odd Man out Practice Test 7

Concept:In a number series, the differences between consecutive terms must follow a consistent pattern.Explanation:Find the differences between consecutive terms.$842 - 839 = 3$$839 - 834 = 5$$834 - 826 = 8$$826 - 815 = 11$$815 - 801 = 14$The differences are $3, 5, 8, 11, 14$.The first difference $3$ breaks the pattern because after $5$, the difference increases by $3$ each time: $5, 8, 11, 14$.So the correct sequence of differences should be $2, 5, 8, 11, 14$.Thus, the first term should be $839 + 2 = 841$, not $842$.So $842$ is the wrong term.Answer:The odd man out is $842$.
