1. 1230
2. 1250
3. 2250
4. 3130

Answer 1

Correct Answer - Option 4 : 3130

Given:

10, 30, 130, 630, ?

Concept Used:

5ⁿ + 5

Calculation:

5⁰ + 5 = 1 + 5 = 6

5¹ + 5 = 5 + 5 = 10 

5² + 5 = 25 + 5 = 30 

5³ + 5 = 125 + 5 = 130

5⁴ + 5 = 625 + 5 = 630

⇒ 5⁵ + 5 = ?

⇒ 3125 + 5

⇒ 3130

∴ The value will come at the place of ? is 3130.
