The recursive formula of an arithmetic sequence is described below. a1= 19, an = An-1 + 6
Which represents the explicit equation of this arithmetic sequence?

A: an= 6n + 13
B: an= 13n + 6
C: an= 19n + 6
D: an= 6n + 19

A(t)=728(1+0.04)^t how much money did aditya originally invest

Read the situations in the table below. then drag a graph and equation to represent each situation. indicate whether each of the relationships is proportional or non-proportional. edit : i got the right answer its attached
