Question Discussion & Solution

The pattern followed in this question is:

0² + 3 = 3

1² + 4 = 5

2² + 5 = 9

3² + 6 = 15

4² + 7 = 23

Calculation∶

The series follows the following pattern

11 + 8 = 19 → 2³

19 + 9 = 28 → 3²

28 + 64 = 92 → 4³

92 + 25 = 117 → 5²

117 + 216 = 333 → 6³

∴ The missing term in the series is 117.

Logic: Alternate Cube and Square of consecutive numbers.

The pattern of given series is:

→ 15 = 7 + 8

→ 27 = 15 + 12

→ 43 = 27 + 16

→ 63 = 43 + 20

The difference increases by 4.

The series follows the following pattern:

346 - 22 = 342

342- 32 = 333

333 - 52 = 308

308 - 72 = 259

259 - 112 = 138

∴ The wrong term in the series is 178.

Calculation:

The series follows the following pattern:

⇒ 79 + 29 = 108

⇒ 108 + 31 = 139

⇒ 139 + 37 = 176

⇒ 176 + 41 = 217

⇒ 217 + 43 = 260

∴ The value of ? is 260

Logic: Addition of Prime numbers
