Please help.

1) Comparing numbers found using different equations requires understanding how to evaluate different equations. Recursive equations require knowing the rst term and using each term to nd the next term. Explicit equations only need to know the term number to evaluate. Use the equations below to answer the questions. an=4n2-7 bn=4(bn_17); b1=5 a) Which equation is the recursive equation? b) How do you know it is the recursive equation? c) Find the 5th term for the equation an = 4:22- 7 . Show all work. If you use a calculator, include all screenshots. d) Find the 5th term for the equation [9,, = 4 (lbw1 7) ; b1: 5 . Show all work. If you use a calculator, include all screenshots. e.) Write a sentence comparing the 5th term for the 2 equations. Be sure to include how much they differ and clearly indicate which isthe recursive and which is the explicit equation
