We are asked to determine the first five terms of the sequence given by the formula an=4n+1, if n is equal to 1 to 5, then an is equal to 5, 9, 13, 17, 21. Answer is A. In 2, given the sequence 8,6,4,2 then the expression is a1=8, an = an-1-2

Answer:1) c. 5,9,13,17,21

2)  a. a1=8, an=an-1 -2

Step-by-step explanation: 1) an=4n+1

    ⇒ a1=4×1+1=5

         a2=4×2+1=9

          a3=4×3+1=13

          a4=4×4+1=17

           a5=4×5+1=21

2) clearly a1=8 and then the terms of series are decreasing by 2

so, an=an-1 -2
