Common difference =

Common ratio =

The common difference applies to the other given numbers for example :

this proves that it is an arithmetic sequence and the given formula for the nth term of an arithmetic sequence is
T_n =a(n-1)d
Where n = no of terms
a= first term
d= common difference
Y = yo + Vot - (gt^2)/2
0 = 0 + 31t - 4.9 t^2
0 = -4.9 t^2 + 31t
