- ans is 336
3^3-3=24
4^3-4=60
5^3-5=120
6^3-6=210
7^3-7=336
its the series

- 2*3*4,3*4*5,4*5*6,5*6*7,6*7*8
- 11 years agoHelpfull: Yes(21) No(0)
- THIS is +36,+60,+90
so 6*(6+0)
next 6*(6+4)
next 6*(6+9)
so it will be 6*(6+15)=126+120=336 - 11 years agoHelpfull: Yes(11) No(11)
- 2*3*4=24
3*4*5=60
4*5*6=120
5*6*7=210
6*7*8=336 - 11 years agoHelpfull: Yes(5) No(0)
- 24 , 60 , 120 , 210 , x
= (3 * 8) , (3 * 20) , (3 * 40) , (3 * 70) , (3 * (x/3) )
Consider (8 , 20 , 40 , 70 , (x/3) )
20 - 8 = 12
40 - 20 = 20
70 - 40 = 30
=> (x/3) - 70 = 42
=> x = 336 - 11 years agoHelpfull: Yes(4) No(7)
- 60-24=36
120-60=60
210-120=90
again 2nd level difference
60-36=24
90-60=30
126-90=36
then finally 210+126=336 is ans
- 11 years agoHelpfull: Yes(1) No(0)
- 6 *4= 24
12*5= 60
20*6=120
30*7=210
42*8=336
as 6+6=12,12+8=20,20+10=30,30+12=42
Ans: 336 - 11 years agoHelpfull: Yes(1) No(0)
