Answer»

The given series is

3, 4, 8, 17, 33, 58, ?

The series is followed by the below pattern

⇒ 3 + 12 = 4

⇒ 4 + 22 = 8

⇒ 8 + 32 = 17

⇒ 17 + 42 = 33

⇒ 33 + 52 = 58

⇒ 58 + 62 = 94

∴ required answer is 94

83, 124, 206, 370, 698, ?1). 13442). 13243). 13644). 1334

Answer»

The pattern of given series is:

→ 83,

→ 124 = 83 + 41 × 1,

→ 206 = 124 + 41 × 2,

→ 370 = 206 + 41 × 4, (4 = 22)

→ 698 = 370 + 41 × 8, (8 = 23)

Based on this pattern, the next TERM will be:

→ ? = 698 + 41 × 16, (16 = 24)

→ ? = 1354

Answer»

47,

47 × 1 - 4 = 43

43 × 4 - 16 = 156

156 × 16 - 64 = 2432

2432 × 64 - 256 = 155392

1). 12842). 12773). 12754). 1279

Answer»

The given SERIES follows the below pattern

1230

1230 + (1 + 2 + 3 + 0) = 1236

1236 + (1 + 2 + 3 + 6) = 1248

1248 + (1 + 2 + 4 + 8) = 1263

1263 + (1 + 2 + 6 + 3) = 1275

∴ ? = 1275

6.

2, 11, 38, 197, 1172, 8227, 658061). 382). 1973). 11724). 8227

Answer»

The pattern of the given number series is as following:

⇒ 2,

⇒ 2 × 3 + 5 = 11,

⇒ 11 × 4 – 6 = 38,

⇒ 38 × 5 + 7 = 197,

⇒ 197 × 6 – 8 = 1174,

⇒ 1174 × 7 + 9 = 8227,

⇒ 8227 × 8 – 10 = 65806

Hence, the WRONG number in the given number series would be 1172.
