Answer:
16
Step-by-step explanation:
Let the fourth term be x.
So,
2:4 = 8:x
As we know that the the product of outer terms I.e. (here) 2 & x, and, The product of inner terms I.e. (here) 4 & 8 are equal. EQ- 1
So,
Product of inner terms,
4×8
32
Product of outer terms,
2×x
2x
According to EQ 1:-
2x=32
x=32/2
x=16
