Option 4: (2, 0)
Correct Answer: (0, 0)
Solution : Given: $y = 3x$ Putting the values of $(x, y)$ from the options, only (0, 0) satisfies LHS = RHS. Thus, it passes through the origin (0,0). Hence, the correct answer is (0,0).
Question : Directions: In the following question a series is given, with one term missing. Choose the correct alternative from the given ones that will complete the series. 127, 131, 137, 139, ?, 151, 157, 163
