Concept:The series should have a constant difference between consecutive terms.Explanation:Check the pattern by adding 9 repeatedly from 841.841+9=850850+9=859859+9=868868+9=877877+9=886In the given series, the second term is 849, but it should be 850.So 849 does not fit the pattern.Answer:849 is the odd term, so Option E is correct.
