Select the number from among the given options that can replace the question mark (?) in the following series.
6, 24, 60, 120, 210, ?
Here the double difference is applicable which is given below.
Let's assume 'y' in place of the question mark.
So 18+6 = 24
24+6 = 30
30+6 = (y-210)-90
36 = y-300
y = 300+36
y = 336
So here '336' will come in place of the question mark.
