Correct Answer: 1200
Solution : Given: 10, 10, 20, 60, 240, ?
Multiply the previous term by consecutive natural numbers, to obtain the next term in the series – 10 × 1 = 10; 10 × 2 = 20; 20 × 3 = 60; 60 × 4 = 240; 240 × 5 = 1200
So, 1200 is the missing term in the series. Hence, the third option is correct.
