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.

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

Divide all numbers with 2 and relate them alternatively hence 18.5 is wrong.

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

36/2=18
54/2=27
18/2=9
27/2=13.5
9/2=4.5
so 18.5 is wrong
54/2=27
18/2=9
27/2=13.5
9/2=4.5
