So since they are similar
AC/BC=CD/CE

so
(66-x)/30=(x+4)/5
times both sides by 5
(66-x)/6=x+4
times both sides by 6
66-x=6(x+4)
distribute
66-x=6x+24
add x to both sides
66=7x+24
minus 24 from both sides
42=7x
divide both sides by 7
6=x
x=6 units

a(n)=a+d(n-1), where a is 1st term, d is common difference, and n it term #

In this case:

a(n)=3.25+0.125(n-1) or more neatly...

a(n)=3.125+0.125n
