Question

If 3,4+p2,6−p  are in A.P.,then p must be equal to

Answer 1

HERE IS YOUR ANSWER

4+p2 - 3 = 6-p -(4+p2)

1+p2 = 6-p-4-p2

1+p2 = 2 -p3

p3+p2 = 2-1

p5 =1

p= 1/5

hope it helps you! !

Answer 2

Answer:

1/2

Step-by-step explanation:

4 + p2 - 3 = 6 - p - (4 + p2)

4 + p2 - 3 = 6 - p - 4 - p2

p2 + 1 = - p2 - p + 2

2p2 + 1 = -p + 2

2p2 + p - 1 =0

Factorize...

2p2 + 2p - p - 1

2p(p + 1) -1(p + 1)

(p + 1) (2p - 1)

p + 1 = 0

p = -1

2p - 1 = 0

p = 1/2

This is your answer
