Answer:
613
Explanation:
nth term equation: an+b
Step 1:find difference between each number in the sequence.
In this case each number decreases by 3
Step 2: subtract 3(diff between each number) from the first number in the sequence to find the 0th term
4-3=1
Nth term= 3n+1
Step 3 : Substitution
3(204)+1
3×204=612
612+1=613
