Answer:Given below

Step-by-step explanation:

Given

a=5

common ratio(r)=1.25

therefore next term is [tex]ar,ar^2....... [/tex]

[tex]a_2=ar=5\times 1.25=6.25[/tex]

[tex]a_3=ar^2=5\times 1.25^2=7.8125 [/tex]

[tex] a_4=ar^3=5\times 1.25^3=9.765[/tex]

[tex]a_5=ar^4=5\times 1.25^4=12.207 [/tex]

[tex]a_6=ar^5=5\times 1.25^5=15.258[/tex]
