-4

Explanation:

This is an arithmetic sequence, where the difference between each two consecutive terms is constant and is called "d" (common difference).

thus we can get the common difference from subtracting any term of the sequence from the term that is before it.

#4-8=-4#

#0-4=-4#

and so on.

#d=-4#

Explanation:

#"the terms form an "color(blue)"arithmetic sequence"#

#"that is "#

#a,a+d,a+2d,a+3d,...... ,a+(n-1)d#

#"where a is the first term and d "color(blue)"the common difference"#

#d=a_2-a_1=a_3-a_2=......=a_n-a_(n-1)#

#"here "d=4-8=0-4=-4#
