Recursive equation for arithmetic sequence

Step-by-step explanation:

A recursive formula takes the previous answer and does something with it to get the next member of sequence.

t_n = t_n-1 + 3  

n≥2

So for t_2 you get t_2 = t_1 + 3

t_1 = - 21

t_2 = -21 + 3 = -18

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
