If 2x, x+10, 3x+5 are in ap find the value of x

A) 5
B) 6
C) 1
D) 2

ANSWER= (A) 5
Explain:-

 

Explanation:

Let ,given 2x,x+10,3x+5

are in A.P

We know if a,b,c are in AP then 2b=a+c

Similarily,

2(x+10)=2x+3x+5

2x+20=5x+5

20-5=5x-2x

15=3x

x=5

If 2x, x+10, 3x+2 are in ap find the value of x

Answer:

Let ,given 2x,x+10,3x+2

are in A.P

We know if a,b,c are in AP then 2b=a+c

Similarily,

2(x+10)=2x+3x+2

2x+20=5x+2

20-2=5x-2x

18=3x

x=6
