He buys 144 bulbs whats the question anyways?
Answer:
-0.26
Step-by-step explanation:
Answer
<span>multiply by 2 and then add 5
1 x 2 + 5 = 2+5 =7
7 x 2 + 5 = 14 +5 = 19
19 x 2 +5 = 38 +5 = 43</span>
150 is the answer I need these points
Find an explicit formula for the sequence 30\,,\,150\,,\,750\,,\,3750,...30,150,750,3750,...30, space, comma, space, 150, space,
OverLord2011 [107]
The series shown is an geometric series and the explicit formula is given by:
an=ar^(n-1)
where
a=first term
n=number of terms
r=common ratio
from the sequence:
a=30
r=5
thus the explicit formula will be:
an=30(5)^(n-1)
hence the answer is:
an=30(5)^(n-1)
