Answer:
common difference = 4
Step-by-step explanation:
<em><u>common difference</u> is</em><em> </em><em>the difference between the successive term and its preceding term.</em>
let's take the successive term of -20 that is - 16
common difference (d) = successive term - preceeding term
= -16 -(-20)
= -16 + 20
=<u> 4</u>
if we take the successive term of -16 that is -12
we'll get the same common difference.
d = -12 -(-16)
d = -12 + 16
d = 4
this means that the common difference for an AP remains constant.
