Name the octant wherein the given points lies: (2,-5,1)

Explanation

To determine the octant in which the point (2, -5, 1) lies, we need to analyze the signs of its coordinates. The three-dimensional coordinate system has eight octants based on the signs of the x, y, and z coordinates.

### Step-by-step Solution:

1. **Identify the coordinates**: The given point is (2, -5, 1).
- Here, \( x = 2 \)
- \( y = -5 \)
- \( z = 1 \)
