Find the first three terms of the sequence described by the following recursive formula: an = 3an – 1 + 2 where a4 = 20 a1= a2= a3=

a1= -2/9

a2= 4/3

a3= 6

Step-by-step explanation:

a_4= 20

lets plug in 4 for n

Subtract 2 from both sides and then divide by 3

18 = 3a_3

lets plug in 3 for n and use a3=6 to find a2

Subtract 2 from both sides and then divide by 3

4 = 3a_2

lets plug in 2 for n and find out a1

Subtract 2 from both sides and then divide by 3

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
