A3=2.6
a4=?
a5=-.4
note that
-2d=-.4-2.6
-2d=-3
-d=-3/2
d=1.5
thus the 4th term is 2.6-1.5=1.1 done

Step-by-step explanation:
There doesnt seen to be a straight up answer for this...
Divide the numerator by the denominator .
Answer:
<em>Similarity doesn't changes angle measures</em>
- ∠U = 56°, ∠U' = 3x - 16
- ∠U = ∠U'
a) 3x - 16 = 56 ⇒ 3x = 72 ⇒ x = 24°
b) ∠T = x + 46 = 24 + 46 = 70°
c) <u>Scale factor:</u>
- k = S'T'/ST = 19/57 = 1/3
<u>Find y using known sides and scale factor:</u>
- U'V'/UV = 1/3
- (y + 4)/63 = 1/3
- y + 4 = 21
- y = 21 - 4
- y = 17
