are you asking for the 9th term or the 10th term?
Meter/ yard. Likely meter since that is high/college standard
4/15 = 0.267
8/25 = 0.32
0.267/0.32 = 0.834375
S is independent variable and T is the dependent variable
A=3
B=4
C=5
Substitute 3 in for 'a' in the equation, and 5 in for 'c' in the equation to get 17.
