Find the middle term of the sequence formed by all three-digit numbers which leave a remainder 5 when divided by 7 . Also find the sum of all numbers on both sides of the middle term separately The base QR of an equilateral triangle PQR lies on x-axis. The coordinates of point Q are (-4,0) and the origin is the mid-point of the base. Find the coordinates if the points P and R x 2 + 6x - (a 2 + 2a - 8) = 0 Two spheres of same metal weigh 1 kg and 7 kg . The radius of the smaller sphere is 3 cm . The two spheres are melted to form a single big sphere. Find the diameter of the new sphere
