Question

hartnn · Answer

the common difference d is just the difference between the consecutive terms.

d= 2nd term - 1st term = 3rd term - 2nd term = ...and so on

hartnn · Answer

here

d = -2 - (-7) = ...
or 
d = 3- (-2) = ...

or 
d = 8-3 = ...

so the D value is basically an equation?

hartnn · Answer

no, its a number
its the difference between consecutive terms

hartnn · Answer

let me give you an example 

10,20,30,40....

here d = 20-10 = 30-20 = 40-30 = $\ \Large 10 $
