A recursive formula is a function of the previous term. The "an-1" is the term that comes before "an".
an arithmetic sequence just adds or subtracts the same number (common difference, d) between terms. looking at the recursive formula it is -9
-35, -44, -53, -62, .....
The explicit formula is a function of the terms place "n" in the sequence. This is written as :
an = a1 + d(n-1)
fill in
a1 = -35 and d = -9
an = -35 - 9(n-1)
expand to
an = -35 - 9n + 9
an = -26 - 9n
Answer:
As shown in picture,
EB is perpendicular with AC
DC is perpendicular with AC
=> EB // DC
Applying Thales theorem:
BC/AC = ED/AD
=> AD = ED x AC/BC = 72 x 88/55 = 115.2
=> AE = AD - ED = 115.2 - 72 = 43.2
Hope this helps!

Answer:
14
Step-by-step explanation:
f(2)=4(2)+2
f(2)=10
g(3)=2(3)-2
g(3)=6-2
g(3)=4
10+4=14
