The numbers the said to be in proportion of the product of there extreme is equal to the product of there mean.
Here, extreme are:- 4 and 90
So, the product of extreme = 4 × 90 = 360
And,
Mean are :- 8 and 16
So, the product of mean = 8 × 16 = 128
Since , Product of extreme ≠ Product of mean
So, they are not in proportion.

Answer:
4 :8 : 16 : 90
They are propoertionate if the product of extreme = product of mean
prodict of extrme =4*90
= 360
Product of mean = 8*16
.= 128
so they are not equal and they are nt propotinate.
