1³ + 2³ = (1 + 2)²

13 + 23 + 3³ = (1 + 2 + 3)²

According to this pattern

13 + 23 + 33 + 4³ + 5³ = ?

1. (1 + 2 + 3 + 4 + 5)² 
2. (1 + 2 + 3 + 4)² 
3. (1 + 2 + 4)²
4. (1 + 2 + 3 + 4 + 5 + 6)²

Answer 1

Correct Answer - Option 1 : (1 + 2 + 3 + 4 + 5)² 

Calculation:

Look at the following pattern:

13 = 1

13 + 23 = (1 + 2)2

13 + 23 + 33 = (1 + 2 + 3)2

According to this pattern

13 + 23 + 33 + 4³ = (1 + 2 + 3 + 4)²

13 + 23 + 33 + 43 + 53 = (1 + 2 + 3 + 4 + 5)²
