## Odd Man Out Series Questions

Dear Reader,

Below are three questions of odd man out series, you have to find the wrong number in each series.

**Question 1**

28, 29, 60, 123, 736, 3685

a)29 b)123 c)736 d)3685

**Answer :** b)123

**Solution :**

The given series are in the following form,

28 x 1 + 1 = 29

29 x 2 + 2 = 60

60 x 3 + 3 = 183

183 x 4 + 4 =736

736 x 5 + 5 =3685

Instead of 183, 123 is given in the series. So 123 is the odd one.

**Question 2**

1853, 925, 461, 229, 113, 55, 11

a)229 b)113 c)55 d)11

**Answer :** d)11

**Solution:**

Each number in the series is obtained by subtracting 3 and divide the result by 2.

1853 - 3 / 2 = 925

925 - 3 / 2 = 461

461 - 3 / 2 = 229

229 - 3 / 2 = 113

113 - 3 / 2 = 55

55 - 3 / 2 = 26

26 - 3 / 2 = 11.5

Clearly, 11 is wrong.

**Question 3**

1900, 1876, 1855, 1837, 1821, 1810, 1801

a)1855 b)1837 c)1821 d)1900

**Answer :** c)1821

**Solution :**

The above series is formed by subtracting multiples of 3 starting from 24 in reverse order.

1900 - 24 = 1876

1876 - 21 = 1855

1855 - 18 = 1837

1837 - 15 = 1822

1822 - 12 = 1810 ... and so on.

The odd one is 1821 which has to be 1822.
