Find the first three terms of the sequence described by the following recursive formula: an = 3an – 1 + 2 where a4 = 20 a1= a2= a3=

a1= -2/9

a2= 4/3

a3= 6

Step-by-step explanation:

a_4= 20

lets plug in 4 for n

Subtract 2 from both sides and then divide by 3

18 = 3a_3

lets plug in 3 for n and use a3=6 to find a2

Subtract 2 from both sides and then divide by 3

4 = 3a_2

lets plug in 2 for n and find out a1

Subtract 2 from both sides and then divide by 3

i can't solve unless i know what the line is
