Solution:

To find the first three terms of the sequence defined as

This implies that we solve for

[tex]a_n[/tex]

for n equals 1, 2, and 3.

Thus,

first term: n=1

[tex]\begin{gathered} a_1=3(1)-8 \\ \Rightarrow a_1=-5 \end{gathered}[/tex]

second term: n =2

[tex]\begin{gathered} a_2=3(2)-8 \\ \Rightarrow a_2=-2 \end{gathered}[/tex]

third term: n = 3

[tex]\begin{gathered} a_3=3(3)-8 \\ \Rightarrow a_3=1 \end{gathered}[/tex]

Hence, the first three terms of the sequence are

[tex]-5,\text{ -2, 1}[/tex]
