The Correct Option is B
Solution and Explanation
Differences of consecutive terms: 27 - 18 = 9, 38 - 27 = 11, 51 - 38 = 13.
The differences increase by 2 each time, so the next differences are 15 and 17.
Missing term = 51 + 15 = 66; check: 66 + 17 = 83, which matches the last term.
Hence the missing number is 66.
Answer: (2) 66
The differences increase by 2 each time, so the next differences are 15 and 17.
Missing term = 51 + 15 = 66; check: 66 + 17 = 83, which matches the last term.

- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
