6, P 14 are consecutive terms in an AP
find the value of P.

In an arithmetic progression, consecutive terms differ by the same value.

So, we have

which reflects the fact that the difference between P and 6 must be the same than the one between P and 14.

The equation solves to

And in fact, if you start with

every pair of consecutive terms differ by 4.

from 1609, galileo galilei used the recently invented telescope to observe the sun, moon and planets. he saw the mountains and craters of the moon, and for the first time revealed the planets to be worlds in their own right. galileo also provided strong observational evidence that planets orbited the sun.

his discoveries about the moon, jupiter's moons, venus, and sunspots supported the idea that the sun - not the earth - was the center of the universe, as was commonly believed at the time.galileo turned his gaze toward venus, the brightest celestial object in the sky - other than the sun and the moon.

b would be the answer
