In a similar segment, what is the fourth equal point from (2) when each part is (\frac{1}{2})?
Answer and explanation
Correct answer: (4)
The governing idea is repeated equal movement along a number line. Starting at 2, each step has length 1/2. After four steps, the total movement is 4×1/2=2 units. Adding this to the starting position gives 2+2=4, so option C is correct. Equivalently, the successive points are 2.5 after one step, 3 after two, 3.5 after three, and 4 after four. Option A stops after two steps, option B after three steps, and option D moves five steps. The wording “fourth point” is interpreted as four equal intervals from the starting point, consistent with the preceding division setup.
