Question Discussion & Solution

The pattern followed by the series is

234 + 4 = 238

238 + 14 = 252

252 + 24 = 276 

276 + 34 = 310 

310 + 44 = 354 

The series follows the following pattern:

1 – 1 = 0

0 + 2 = 2

2 – 1 = 1

1 + 2 = 3

3 – 1 = 2

∴ The missing term in the series is 3.

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

⇒ 10² + 20 = 120

Given series:

5, 15, 50, ?, 1030, 6185

Calculation:

The series is following the below pattern,

5 × 2 + 5 = 15

15 × 3 + 5 = 50

50 × 4 + 5 = 205

205 × 5 + 5 = 1030

1030 × 6 + 5 = 6185
