d
Step-by-step explanation:
<u>Answer:
</u>
Required value of f(0) = 4 and common difference of given sequence is 
<u>Solution:
</u>
Given sequence rule for arithmetic sequence is 
We need to determine f(0) and common difference
Calculating f(0).
Substituting x = 0 in given sequence rule we get

Calculating common difference
Let’s first calculate f(1) and f(2).
Substituting x = 1 in given sequence rule


Common Difference can be found by subtracting f(1) from f(2)

Hence required value of f(0) = 4 and common difference of given sequence is 
Get x by itself
add 16 to both sides, so 4x = 16
divide both side by 4 and x =4
