# Question: use the following data values at time 13 observed position...

###### Question details

Use the following data values:

At time 13, observed position was (1, 3, 7)

At time 84, observed position was (23, -5, 10)

You want to find the position at time 50"

**My question is; what equation can I use to solve for
[x3, y3, z3] knowing [t1, x1, y1, z1,] and [t2, x2. y2, z3] and
[t3]?**

**Is there a Python function I can use for
this?**
