odd one out !!15, 16, 22, 29, 45, 70I don't have the ans so pls explain whoever solve this...as i'm feeling very sleep now

1) 16
2) 22
3) 29
4) 45
5) 70
6) 15

• 22
  since
  16-15=1=1^2
  20-16=4=2^2 (according to que it is 22 which is wrong)
  29-20=9=3^2
  45-29=16=4^2

• 29 is add as it is a prime number.

• 29 would be the answer... all else have multiple. 29 only is the prime number amongst them

• If we see the difference b/w the no.s are (16-15)=1,(22-16)=6 and similarly 7,16,25.all the nos are squares of 1,_,_,4,5.so if the difference is of 4 instead of 2 then the next difference will be 9 and hence it completes the series.so instad of 22 there should be 20.

• 45 is the odd one.
  see:
  15 + 1=16
  16 + 6=22
  22 + (6+1=7)=29
  29 + (7+6+1=14)=43 (not 45)
  43 + (14+7+6=27)=70
