Question

If 7P-2, 5P - 8 and P +1 are in AP then p is equal to?
​

Answer 1

Step-by-step explanation:

AP are

7p-2, 5p-8, p+1

d=5p-8-7p+2=-2p-6

as we know

a2= a+(3-1)d

by putting value

5p-8=7p-2+2(-2p-6)

5p-8=7p-2-4p-12

5p-8=3p-14

5p-3p=-14+8

2p=-5

p=-5/2

Answer 2

Answer:

solution :-

Step-by-step explanation:

7

$7x - 2 + x + 1 = 5x - 8 + x + 1 = 8x - 1 = 6x - 7 = 2x - 6 = x = 6 \div 2 = 3$
