Question

U

Answer 1

Answer:

Step-by-step explanation:

$a(n) = a1 *(1.25)^{(n-1)}$

$a(1) = 5$

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

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

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

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

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

$a(1) = 5$

$a(2) = 6.25$

$a(3) = 7.813$

$a(4) = 9.766$

$a(5)=12.207$

$a(6)=15.259$
