										Hello student,
Please find the answer to your question below
Given(ax-b)*(cx-d)/(bx-a)*(dx-c)
=(acx2-(ad+bc)x+bd)/bdx2-(bc+ad)x+ac
=x2-((d/c)+(b/a))x+(bd/ac)/x2-((c/d)+(a/b))x+(ac/bd)
So by finding the discriminant of the equation from the above we can observe that
the expression (ax-b)*(cx-d)/(bx-a)*(dx-c) can have all the values for real x if (a*a)-(b*b) and (c*c)-(d*d) have the same sign.

The series will be 45, 41, ?, 50, 25, 29 4 2 + 5 2 = 41 4 2 + 1 2 = 17 1 2 + 7 2 = 50 5 2 + 0 2 = 25 2 2 + 5 2 = 29 So, in place of ?, the number will be 17

= 29 2 + 5 2 = 252 2 + 0 2 = 505 2 + 7 2 = 171 2 + 1 2 = 414 2 + 5 2 The series will be 45, 41, ?, 50, 25, 294 so number is 17(seventeen)
