Answer:
x = 2
Step-by-step explanation:
First, you cross multiply then that will give you
9x - 3 = 5x + 5
collect like terms
9x - 5x = +5 + 3
= 4x = 8
Divide both sides by the coefficient of x that's 4
= 2

Answer:
Option A.
Step-by-step explanation:
The given sequence is
24, 30, 36, 42, 48, ...
It is an AP. Here,
First term = 24
Common difference = 30-24 = 6
The given explicit formula for nth term is
where,
is first term, d is common difference.
Substitute
in the above formula.
The 500th term of the sequence is 3018.
Therefore, the correct option is A.
