Question

If x+2,3x,4x+1 are in ap find x

Answer 1

Answer:

The answer is $x=3$

Step-by-step explanation:

Concept: if three numbers $a,b,c$ are in A.P., then

      $\boxed{b-a=c-b\Rightarrow 2b=a+c}$

Here given $x+2,3x,4x+1$ are in A.P.

      $\Rightarrow 2(3x)=x+2+4x+1\\\Rightarrow 6x=5x+3\\\Rightarrow 6x-5x=3\\\Rightarrow x=3$
