Answer:
The sum of the first twenty-seven terms is 1,188
Step-by-step explanation:
we know that
The formula of the sum in arithmetic sequence is equal to
where
n is the number of terms
a1 is the first term
d is the common difference (constant)
step 1
Find the common difference d
we have
n=7
a1=-8
S=28
substitute and solve for d
step 2
Find the sum of the first twenty-seven terms
we have
n=27
a1=-8
d=4
substitute
100
A. 10
B. 1001/2
C. 5
D. -1001/2
E. -10
E. 50
