Select the explicit expression for the sequence {4, 9, 14, 19...}. f(n)=4+5(n−1)

f(1)=4, f(n)=f(n−1)+5 for n>1

f(1)=5, f(n)=f(n−1)+4 for n>1

f(n)=5+4(n−1)

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.

multiply each one by 3.14
