Step-by-step explanation:
The sequence is as follows :
-59 ,-67 ,-65 ,-53 ,-31 ,...
The first term = -59
The second term = -67
Common difference = second term - first term
[tex]=-67-(-59)\\\\=-8[/tex]
To calculate the second term add (-8).
To calculate each additional term, increase the amount added by -8.
