Discussion :: Odd Man Out and Series  Pick Wrong No. (Q.No.4)
Find out the wrong number in the given sequence of numbers.
4.  1, 8, 27, 64, 124, 216, 343 

Answer: Option D Explanation:
The numbers are 1^{3}, 2^{3}, 3^{3}, 4^{3} etc. So, 124 is wrong; it must have been 5^{3} i.e., 125.

1*1*1=1. 2*2*2=8. 3*3*3=27. 4*4*4=64. 5*5*5=125. 6*6*6=216. 7*7*7=343. 124 is not a perfect cube of any number.

1 8 27 64 124 216 343. a:1 = 1. 8 = 8. 27=2+7=9. 64=6+4=10=1+0=1. 124=1+2+4=7. 216=2+1+6=9. 343=3+4+3=10=1+0=1. Here the series is 1 8 9 1 8 9 1 8 9 but here second 8th position is occupied by 7. So the wrong number is 124.

Is it correct if we see it this way? 1odd. 8even. 27odd. 64even. 124even. 216even. 343odd. So there should be an odd number between 64 and 216 to maintain the oddeven series hence 124 is wrong.
