Correct option is D
Given: 240, 240, 120, 40, 10, ?
Look at the pattern in the sequence:
From 240 to 240: divide by 1 (240÷1 = 240).
From 240 to 120: divide by 2 (240 ÷ 2 = 120).
From 120 to 40: divide by 3 (120 ÷ 3 = 40).
From 40 to 10: divide by 4 (40 ÷ 4 = 10).
Following this pattern, the next step would be to divide 10 by 5:
10 ÷ 5 = 2
The answer is (d) 2.
