Question

Find the odd man out of the series 19,37,73,145,217,285

Answer 1

19 as it is the only 2 digit number

Answer 2

Here we sind the pattern of the given series.

First term is = 19

Second term is = 19 + (19-1) = 37

Third term is = 37 + (37-1) = 73

Forth term is = 73 + (73-1) = 145

Fifth term is = 145 + (145-1) = 289

but in given sequence fifth term is 217

So, odd man out of the series is fifth term 217.
