find the odd one 17,25,32,37,47,59,71

Question

if i simply observe all no is odd except 32 so my answer should be 32  bt if i do other observation like 17 do digit sum ie (1+7)=8 and it is the diffrence between 17 and 25 and then if i take 25 do digit sum i got 7 and it is the diffrence between 25 and 32 like wise i do my procedure and i got 59 odd one then which one is correct in 32 and 59.  

• A. 32
• B. 59
• C. 71
• D. 47
• E. 37

Answer should be 32. question asking to find odd one.Here you have to check each number individually.You can' t relate them.He is not asking like what is the next number in series.

Answer 1

although both of ur reasons are true your second argument is more strong so ans should  be 59 (b)

how can u judge second  one is strong

---

first one is easily observable by everyone . they dont have to give so many numbers for that and second one is observed in all 7 numbers which can not be just coincidence (without logic). and bottom line is that the logic which examiner set is right we can do nothing about it

Answer 2

ur second observation seems not to be true.

since, 4+7=11. but the difference between 47 and 59 is 12. Again 5+9=14. but the difference between 59 and 71 is 12.

so, according to ur second observation, we got two odd ones.

hence, 32 must be the answer

That's why 59 is odd one. If you place 58 in place of 59..then above logic seems verifying this series.

4+7=11. and diff between 58 and 47 is also 11. now next  5+8= 13 and 71-58= 13. so i think 59 is odd one.
