Webx = y = z Solution: As x,y,z are in A.P. ⇒ 2y = x+ z ... (i) tan−1x,tan−1 y and tan−1 z are also in A.P., then 2tan−1 y = tan−1 x,+tan−1z 2tan−1 y,+tan−1(1−xzx+z) ⇒ tan−1 (1−y22y) = tan−1 (1−xzx+z) Thus y2 = xz ... (ii) From (i) and (ii), we get x = y = z. Remark : y = 0 is implicit to make any of the choice correct. Web(i) The value of `x + y + z` is 15. If a, x, y, z, b are in AP while the value of `(1)/(x) + (1)/(y) + (1)/(z) \" is \" (5)/(3)`.
