Answer:
Recursive formula is [tex]a_n = (a_{n-1} *3) + 2[/tex]
Step-by-step explanation:
8, 26, 80, 242, . . .
8 is the first term
To get 26 we multiply 8 by 3 and then add 2
8*3 = 24 + 2= 26
26 * 3= 78+2 = 80
80*3 = 240 + 2 = 242
So to get next term we multiply the previous term by 3 and then we add 2
[tex]a_n = (a_{n-1} *3) + 2[/tex]
