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

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
