Answer:
what is your questions
Answer:
There is no logic in this series.
I will interpret that middle of the first three numbers is the average of the three numbers.
( 120 + 80 + 40 ) / 3 = 80 ,
Similarly (45 + x + 5 )/ 3 = x
So x = 25.
If in the book it were written as x = 25 .
Everyone will answer like this .
A series must be such that one should be able to say how 45 came after 40 ?
If they use two or more series, it should be expressed.
What will be the X in the series, 120, 80, 40, 40, 45, X, 5, and why?
What is the next number in the pattern of 120, 80, and 40?
What will be the value of 'x' in this series 15, 15, 30, 10, 40, x, 48?
748, 737, 715, 682, 638, x, What is the value of x in the given series?
1,4,14, 45, 139, x, find the value of x in the given series?
120
80 (80/120= 2/3 =2×1/3
40 (40/120=1/3))
3rd number /1st number = 40/120=1/3
45
15 15/45=1/3
5 5/15= 1/3
similarly ratio of last number 5 and number 15
5/15=1/3
15 is right answer

120, 80, 40, 45, X, 5
First three things are taken as base hence we have 45>40 then rest are smaller.
120, 80, 40, (120*3/8)/1, (80*3/8)/2, (40*3/8)/3
120, 80, 40, 45, 15, 5
120×5=600,80×X=?,45×40=1800
If u look at the above one u can figure out that the missing no(?) Is 1200
Therefore 80×X=1200
Which implies X to be 15
