Answer:
x = - 7
Step-by-step explanation:
Given that the terms are in AP , then
a₃ - a₂ = a₂ - a₁ , substitute values
3x + 4 - (2x - 1) = 2x - 1 - (2x + 1) ← distribute and simplify both sides
3x + 4 - 2x + 1 = 2x - 1 - 2x - 1
x + 5 = - 2 ( subtract 5 from both sides )
x = - 7
So with this, you'll be using a proportion to solve it. And here's what your equation will look like:
Firstly, you'll need to cross-multiply. Your equation will look like this: 
For this, all you need to do is square root, and your answer is 
, however this answer can be simplified further.
In short, your answer is
