Answer:
c
Step-by-step explanation:
Answer:
This is a sequence where you <em>multiply that number 3 times</em>. For example, 2 x 3 = <em>6</em>. 6 x 3 = <em>18</em>. 18 x 3 = <em>54</em> and so on. Therefore, <em>multiplying 3 by the number is the Answer.</em>
<em></em>
You replace x with (a+1)
Then f(a+1) = (a+1)^2+1
= a^2+2a+1+1
= a^2+2a+2
Your answer will be 0.67
