Question

If 3,4+p and 7-p are in A. P., then find the value of p

Answer 1

let a=3,b=4+p,c=7-p are in A.P
then 2b=a+c
2(4+p)=3+(7-p)
8+2p=3+7-p
2p+p=10-8
3p=2
p=2÷3

Answer 2

Answer:

p =2/3

Step-by-step explanation:

Given :  3,4+p and 7-p

To Find: Value of p

Solution:

Since  3,4+p and 7-p are in A.P.

So, $d=7-p-(4+p)=(4+p)-3$

So, $7-p-4-p=4+p-3$

$3-2p=1+p$

$2=3p$

So, p = 2/3
