1.If x,y,zx, y, zx,y,z are in arithmetic progression with common difference ddd, y=x+3dy = x + 3dy=x+3d, and the determinant of the matrix∣342x452ykz2∣=0,\begin{vmatrix} 3 & 4\sqrt{2} & x \\ 4 & 5\sqrt{2} & y \\ k & z & \sqrt{2} \end{vmatrix} = 0,34k4252zxy2=0,then the value of k2k^2k2 is:a.727272b.121212c.363636d.666Login to continueOnly logged in users canattempt or see the solution.
