Wrong%20Number%20Series

Answer :

The series is

50 + 1² = 51,

51 - 2² = 47,

47 + 3² = 56,

56 - 4² = 40,

40 + 5² = 65,

65 - 6² = 29.

Hence, there should be 40 in place of 42.

Answer :

The series is 3 x 2 + 3 = 9,

9 x 3 - 4 = 23,

23 x 4 + 5 = 97,

97 x 5 - 6 = 479,

479 x 6 + 7 = 2881,

2881 x 7 - 8 = 20159

Hence, there should be 97 in place of 99.

Answer :

The series is x0.5 + 0.5,

x1 + 1,

x 1.5 + 1.5,

x 2 + 2,

x 2.5 + 2.5,

x 3 + 3...

Hence, there should be 5 in place of 6

Answer :

The series is 1 x 2 + 1 = 3,

3 x 2 + 0 = 6,

6 x 2 - 1 = 11,

11 x 2 - 2 = 20,

20 x 2 - 3 = 37,

37 x 2 - 4 = 70.

Hence, there should be 37 in place of 39.

Answer :

The series is 2 x 2 + 7 = 11,

11 x 3 - 6 = 27,

27 x 4 + 5, = 113,

113 x 5 - 4 = 561,

561 x 6 +

3  = 3369,

3369 x 7 - 2 = 23581.

Hence, there should be 11 in place of 13.
