- The series is 2,2,4,12,48. The first number is 2. Let us keep it aside. The logic used in this series is: the second number is equal to the product of first number multiplied with n( n starts from 1). So second term = 2 * 1 = 2. Third term = second term * 2 = 2*2 = 4. Fourth term = 4*3 = 12. The logic again is : previous term * (n+1). Hence, the next term is 48*5 = 240

- 2,2,4,12,48,__
2*2=4
in the nxt step(the elements can be taken)=(2,2,4)=4*3=12
and we take these 4 numbers can be multiplied by 12=12*4=48
and these 5 numbers can be multiplied by 48=48*5=240
and finally the answer is==240 - 4 years agoHelpfull: Yes(0) No(0)
- 48/12=4
12/4=3
4/2=2
2/2=1.......
so
240/48=5 - 4 years agoHelpfull: Yes(0) No(0)
- 280,
2*1=2
2*2=4
4*3=12
12*4=48
next one should be multiplied with 5
so,48*5 = 280 - 4 years agoHelpfull: Yes(0) No(0)
- 12*48 = 576
- 3 years agoHelpfull: Yes(0) No(0)
