Step-by-step explanation:
To find the sum of a finite geometric series, use the formula,
Sn= a1-a1r^n/ 1-r
where n is the number of terms, a1 is the first term and r is the common ratio .
common ratio = a2/a1
S8=3-3(-2/3)8 / 1-(-2/3)
S8 = 3-(-2)8/ 1+ 2/3
S8= 3-256/ 3+2/3
S8= -253/5/3
S8= -253*3/5
S8= -759/5
