I read it as whatever was being added to it, the double of it was deducted from it so according to me 18 added 36 deducted 9 added 18 deducted therefore when 9.5 was added 19 should have been deducted & 4.5 would be wrong & -0.5 could be the answer instead of 4.5 & I conclude that I considered 4.5 wrong!

I just don't get it ! Maybe I have an IQ.
I answered 4.5. All the other numbers individually add up to '9'.

Agree @Nagendramurthy.
(5 + 4) = 9
(3 + 6) = 9
(2 + 7) = 9
(1 + 8 + 5) = 14
(5 + 4) = 9
(3 + 6) = 9
(2 + 7) = 9
(1 + 8 + 5) = 14

Forget the decimal point then every number sums up 9 except 18.5 so it is wrong.

54 - 36 = 18 next no.
27 - 18 = 9 next no.
13.5 - 9 = 4.5 next no.
So 18.5 wrong.
27 - 18 = 9 next no.
13.5 - 9 = 4.5 next no.
So 18.5 wrong.

Every term will be divisible by 9 except 18.5.
So 18.5 is wrong.
So 18.5 is wrong.

1 and 2 number is the multiple of 3rd number and so on, but 18. 5 doesn't satisfy this condition i.e (18, 18*2=36, 18*3=54) (9, 9*2=18, 9*3=27) (4.5, 4.5*2=9, 4. 5*3=13.5). There should be 13.5 instead of 18.5.

All the numbers in the table are multiples of 4.5 i.e( all the terms in the table satisfy the table of 4.5 except 18.5).
Hence the answer is 18.5.
Hence the answer is 18.5.

18.5 cannot be divided by 9 while others can be divided by 9.
So answer is 18.5.
So answer is 18.5.
