In the following question, one term in the number series is wrong. Find the wrong term. 3, 2, 8, 12, 13, 24, 18, 32, 23, 42
The given series is a combination of two series. I: 3 8 13 18 23 II: 2 9 24 32 42 In I, the pattern is + 5, in II the pattern is + 10 The wrong number here is 24 in series II. The correct number should be: 12 + 10 = 22
2, 5, 9, 19, 37, ?
In this series, we have, 2 x 2 + 1 = 5 5 x 2 - 1 = 9 9 x 2 + 1 = 19 19 x 2 - 1 = 37 So, the next term is 37 x 2 + 1 = 75
1, 4, 27, 16, 125, ?, 343
The given series consists of cubes of odd numbers and squares of even numbers i.e. 13, 22, 33, 42,… The next term is 62 = 36
1, 11, 34, 77, 143, ? ]
1, 11, 34, 77, 143, ?
The given series is a triangular pattern series series The next term should be – 143 + (66 + 23 + 5 ) = 143 + 94 = 237
2, 3, 3, 5, 10, 13, 39, ?, 172, 177
The pattern in the given series is: +1, x1, +2, x2, +3, x3, +4, x4, +5, x5 ….. The missing number should be: 39 + 4 = 43
