Answer:

Explanation:


a(n) = a1 *(1.25)^((n-1))


a(1) = 5


a(2) = 5*(1.25)^((2-1))\\a(2) = 5*(1.25)^(1)\\a(2) = 5*(1.25)\\a(2) = 6.25


a(3) = 5 * (1.25)^((3-1)) \\a(3) = 5 * (1.25)^(2)\\a(3) = 5 * 1.565\\a(3) = 7.813


a(4) = 5* (1.25)^((4-1))\\ a(4) = 5* (1.25)^(3)\\a(4) = 5* 1.953\\a(4) = 9.766


a(5) = 5 * (1.25)^((5-1))\\a(5) = 5 * (1.25)^(4)\\a(5) = 5 * 2.441\\a(5) = 12.207


a(6) = 5 * (1.25)^(5)\\a(6) = 5 * 3.052\\a(6) = 5 * 3.0517\\a(6) = 15.259


a(1) = 5


a(2) = 6.25


a(3) = 7.813


a(4) = 9.766


a(5)=12.207


a(6)=15.259
