Answer:
= 3n + 3
Step-by-step explanation:
The sequence is arithmetic with explicit formula
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
From the recursive formula
a₁ = 6 and d = 3 [ the constant being added to A(n - 1) ] , then
= 6 + 3(n - 1) = 6 + 3n - 3 = 3n + 3

Answer:
A, D and E
Step-by-step explanation:
The diagram is drawn and attached below.
Writing it backwards:
Also,
Therefore, A, D and E are the similarity statements that describe the relationship between the two triangles.
