Q. What is the next number of the following sequence
2,1/3,2/3,6,7,1/2,7/2,14,20,1/5,4
Read Solution (Total 8)
-
- the series must be divided in equal parts of 4 terms each,
First part
2*1/3=2/3
2*3=6
second part
7*1/2=7/2
7*2=14
third part
20*1/5=4
20*5=100
Hence 100 is the answer

- As per the series
2*1/3=2/3 and then 2*3=6
7*1/2=7/2 and then 7*2=14
in the same way for
20*1/5=4 and then 4*1=4
Finally 4 is the answer - 10 years agoHelpfull: Yes(26) No(12)
- divide it into 4 seperate parts
2 1/3 2/3 6 (2*3=6)
7 1/2 7/2 14 (7*2=14)
20 1/5 4(20/5 or it cn b write as 4/1) ? ( 4*1=4) - 10 years agoHelpfull: Yes(7) No(0)
- 4 can be written as 20/4 ..
2*3=6
7*2=14
20*5=100
so ans is 100 - 10 years agoHelpfull: Yes(4) No(11)
- 2*1/3=2/3
2*3=6
7*1/2=7/2
7*2=14
20*1/5=4
20*1=20 - 7 years agoHelpfull: Yes(2) No(1)
- [ 2 + (1/3 + 2/3) ] + 3 = 6 (Present At 4th position)
[ 7 + (1/2 + 7/2) ] + 3 = 14 (Present At 8th position)
[ 20 + (1/5 + 4) ] + 3 = 136/5 (will be Present At 12th position) Ans: 136/5 It is also a logic check - 8 years agoHelpfull: Yes(0) No(1)
- Break it into sections:
2,1 3,2 3,6,7,1 2,7 2,14,20,1 5,4
So there are 6 parts and the 2 preceding parts are inputs.
How are the four numbers generated.
1. First num second pair
2. Multiply second pair
3. Multiple + second number of first pair
4. Last num of first pair
first number of second pair = 3
Multiply 3*2 = 6
Multiply + 1 (last number of first pair)
Last number of first pair 1
2,1 3,2 == 3,6,7,1
first number of second pair = 2
Multiply 7*2 = 14
Multiply + 6(second number of first pair) 14+6 = 20
Last number of first pair 1
3,6,7,1 2,7 == 2,14,20,1
So the first number of the second pair is 5; 5 is the answer. - 7 years agoHelpfull: Yes(0) No(1)
- 2*1/3=2/3
2/1/3=6
6*1/2=3
6/1/2=12
7*1/2=7/2
7/1/2=14
20*1/5=4
20/1/5=100 ans - 7 years agoHelpfull: Yes(0) No(0)
