Answer:

161

Step-by-step explanation:

<u>Given:</u>

a_1=1\\ \\a_n=3a_{n-1}+2

<u>Find:</u> a_5

First, find the second term. Substitute n=2:

a_2=3a_1+2=3\cdot 1+2=3+2=5

Now, find the third term, substitute n=3:

a_3=3a_2+2=3\cdot 5+2=15+2=17

Find the 4th term, substitute n=4:

a_4=3a_3+2=3\cdot 17+2=51+2=53

At last, find the fifth term, substitute n=5:

a_5=3a_4+2=3\cdot 53+2=159+2=161
