Answer:
See below
Step.-by-step explanation:
Choice A has first term -3 and common difference 5. The formula for the kth term is -3 + (k - 1)5. It is an arithmetic series.
The required expanded form for the Sum is:
5
S5 = ∑ [-3 + (k - )5)]
k = 1
Answer:
Expanded form of the series is:
A. -3 + 2 + 7 + 12 + 17
Step-by-step explanation:
when k=1 -3+(k-1)5= -3
when k=2 -3+(k-1)5= -3+5=2
when k=3 -3+(k-1)5= -3+10=7
when k=4 -3+(k-1)5= -3+15=12
when k=5 -3+(k-1)5= -3+20=17
Hence, value of [tex]S_{5}= -3+2+7+12+17[/tex]
Hence, expanded form of the series is:
A. -3 + 2 + 7 + 12 + 17
