Mathematics

Arithmetic Sequence Formula:

a_n=a_1+(n-1)d

We have:

a_1=-11,\ a_2=-3,\ a_3=5,\ a_4=12,\ ...

d=a_{n+1}-a_n\to d=-3-(-11)=-3+11=8

Substitute:

a_n=-11+(n-1)(8)=-11+8n-8=8n-19

Answer: a_n=8n-19

How do I solve for h
WITCHER [35]
All the triangles are similar, so the ratio of (long leg)/(short leg) is the same. The long leg of ΔADB is
.. AD = AC -DC = 20 -4
.. AD = 16

Then
.. (long leg)/(short leg) = AD/DB = BD/DC
.. 16/h = h/4
.. h^2 = 64
.. h = 8

Selection D is appropriate.

_____
You may see this again. The altitude (h) from the right angle in a right triangle is the geometric mean of segments AD and DC. That is,
.. h = √((AD)*(DC))
