We're given the Arithmetic Progression <em>-24, -4, 16, 36 ...</em> .
We know that a term in an AP is generally represented as:

where,
- a = the first term in the sequence
 - n = the number of the term/number of terms
 - d = difference between two terms
 
We need to find 
.
From the given progression, we have:
- a = -24
 - n = 23
 - d = (-24 - (-4) = -20
 
Using these in the formula,

Therefore, the 23rd term in the AP is -464.
Hope it helps. :)
 
        
             
        
        
        
In a quadratic equation with the general formula of:
ax^2 + bx + c = 0
The discriminant is equal to b^2 - 4(a)(c). If the answer is a perfect square, then there are two real numbers. If not, then there are no real number root.
The discriminant for this equation is
(-6)^2 - 4(3)(1) = 24
Since 24 is not a perfect square, there are no real number roots.
