1. 2
2. 4
3. 1
4. - 8
5. 8

Answer 1

Correct Answer - Option 5 : 8

Given:

256, 32, 8, 4, 4, ?

Calculation:

The logic follows here is;

256 ÷ 8 = 32

32 ÷ 4 = 8

8 ÷ 2 = 4

4 ÷ 1 = 4

By observing the above pattern, we can write

4 ÷ 0.5 = ?

⇒ 4 ÷ (1/2) = ?

⇒ 4 × 2 = ?

⇒ ? = 8

∴ 8 should come in place of the question mark (?).
