Your Answer:
As Given ;
2,band 8 are in continued proportion and we have to find value of b .
2,b and8 =2:b::b:8
_____________________________
$\boxed{Rule\: of\: proportion:-}$
•Product of extremes =Product of means
______________________________
Here Product of extremes is 8×2
And Product of means is b×b
So ,
8×2=b^2
=>b^2=16
=>b=√16
=>b=4
So answer is 2:4::4:8
