Question

If p – 1, p + 3, 3p – 1 are in AP, then find the value of p .

Answer 1

Answer:

p = 4

Step-by-step explanation:

given ,

the values are in A.P,

so that , we can use the formulaa

      t2-t1 = t3-t2

(p+3)-(p-1) = (3p-1) - (p+3)

p+3-p+1     = 3p-1-p-3

   4           =    2p - 4

   2p= 4+4

      p = 8/2

      p= 4
