How to know if it is a Linear and Recursive:
look at the differences between each term in the table. For the 1st difference you will have to subtract each term to find the common difference.
Use the nth term and add the common differences
Therefore the answer would be f(1)=-3 f(n)=f(n-1)-4
How to find Explicit Equation:
Find the common difference and add the 0th term
therefore the answer would be f(n)=-4n+1

How to know if it is a Exponential and Recursive Equation:
look at the differences between each term in the table, if the numbers do not match then continue on looking at the differences in the 1st, 2nd, and 3rd. For the 3rd differences you will have to multiply the differences or else it would be undetermined.
Therefore the answer would be f(1)=6 f(n)=f(n-1)*2
How to find Explicit Equation:
find the 0th term in the table, then multiply the common difference^n
therefore the answer would be f(n)=3*(2)^n

How to know if it is a quadratic:
look at the differences between each term in the table, if the numbers do not match then continue on looking at the differences in the 1st difference. If the 2nd difference matches then you will know that it is quadratic.
How to find Recursive Equation:
after looking at the differences between each term use the 2nd difference * n add or subtract to look at each term.
Therefore the answer would be f(1)=0 f(n)=f(n-1)+2n-1
How to find Explicit Equation:
use n^2 multiply or add or subtract the term. plug in the points to find the common difference(answers varies depending) depending on the question.
therefore the answer would be f(n)=n^2-1
