The answer is Letter B - 2, 8, 26

<span>Given: an=3an-1+2 ; where a2=8
Required: First three terms of the sequence - a1, a2, a3
Solution:

You need to work back to get a1 since the given is a2.</span><span>
To work back, minus 2 from 8 first before dividing the number by 3. 
 a1 = 8 - 2
 a1 = 6 / 3
 a1  = 2

In getting a3, multiply the given 8 by 3 then add 2. </span>an=3an-1+2 : a3=3(8)+2<span>
a3 = 8 x 3
a3 = 24 + 2
a3 = 26</span>
