8 wooden

8 wooden poles are used for pillers and length of the pillers are from an arithemetric progression if the second pole is 2 metre and the sixth pole in order 5 meters, find the different between the sixth pole and seventh pole.

Correct answer:

d =  0.75 m

Step-by-step explanation:

a2=2 m a6=5 m  a6=a2+4d  d=a6a24=524=34=0.75   Verifying Solution:  d=a7a6=34 m=0.75 m
