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) x = 5
b) x = 4
Step-by-step explanation:
a) = 9.5
3x+4 = 9.5(2)
3x = 19-4
x = 15/3
x = 5
b) = 5
7+2x = 5(3)
2x = 15-7
x = 8/2
x=4
