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

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)

[ 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

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.
