Answer:

Find the value of x, if 8,x, x, 50 are in proportion.

If a,b,c and d are in proportion then we have a/b = c/d

Now we need to find the value of x given if 8, x, x, 50 are in proportion.

So we have 8/x = x/50

Or x x x = 8 x 50

Or x^2 = 400

Or x = ±√400

Or x = ± 20

Therefore the value of x will be + 20 or - 20
