126*2=252
Answer:
speed = 
Step-by-step explanation:
using the formula that relates distance/ speed/ time
distance = speed × time
hence speed =
= 
-50 + 17 = - 33
-33 + 17 = -16
- 16 +17 =1
This is arithmetic sequence, where 1st term is -50,
and common difference is 17.
Formula for the term of arithmetic sequence
a(n) = a(1) +d(n-1) = -50 +17(n-1) = -50 +17n - 17 = -67 +17n
So, we can write a formula
a(n) = -67 +17n
The correct answer is a because -50 is closer to zero than any other number
Hope this helps!
