Question Discussion & Solution

The series follows the following pattern:

12 + 11 = 23

23 + 22 = 45

45 + 33 = 78

78 + 44 = 122

122 + 55 = 177

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

Additional Information

The pattern of the series is

6 × 3 + 1 = 19

19 × 3 + 2 = 59

59 × 3 + 3 = 180

180 × 3 + 4 = 544

544 × 3 + 5 = 1637 

Calculation:

The series follows following pattern:

⇒ 5 + 0 = 5

⇒ 5 + 5 = 10

⇒ 10 + 10 = 20

⇒ 20 + 15 = 35

⇒ 35 + 20 = 55

⇒ 55 + 25 = 80

∴ The missing number is 80
