what is the common difference between successive terms in the sequence? 9, 2.5, -4, -10.5, -17, ... -11.5 -6.5 6.5 11.5
Answer
Explanation:
Step1: Subtract first term from second term
$2.5 - 9=-6.5$
Step2: Check with other consecutive terms
$-4 - 2.5=-6.5$ $-10.5-(-4)=-10.5 + 4=-6.5$ $-17-(-10.5)=-17 + 10.5=-6.5$
Answer:
B. -6.5
