Let a(0) represent the first term; its value is -10.  The next term is found by subtracting 2 from -10, obtaining -12.  Each new term is created by subtracting 2 from the previous one.  Thus, the formula for the nth term is

a(n) = a(0)-2(n-1), or a(n) = -10-2(n-1).

First term:  -10

Second:  -12

Third:  -14,

....

Tenth term:  a(10) = -10-2(10-1) = -10 - 18 = -28

17. RQ is the same as PS.
PS = -1 + 4x
RQ = 3x + 3
-1 + 4x = 3x + 3
4x = 3x + 4
x = 4
Now plug that into RQ.
3(4) + 3 = RQ
15 = RQ

18. Angles G and E are equal to each other.
G = 5x - 9
E = 3x + 11
5x - 9 = 3x + 11
5x = 3x + 20
2x = 20
x = 10
Plug that x into G.
5(10) - 9
41 = G

19. TE and EV are equal to each other.
TE = 4 + 2x
EV = 4x - 4
4 + 2x = 4x - 4
2x = 4x - 8
-2x = -8
x = 4
Plug that into TE.
4 + 2(4)
12 = TE

20. DB and BF are equal.
DB = 5x - 1
BF = 5 + 3x
5x - 1 = 5 + 3x
5x = 6 + 3x
2x = 6
x = 3
Plug that into DB.
5(3) - 1
14 = DB
