Sum of aritmetic sqeuqnece is
(n/2)(a1+an)
a1=first term
an=nth term
n=how many terms
so we gots
a1=3(1)-4=-1
a18=50
n=18
(18/2)(-1+50)
(9)(49)
441
other one
a1(1-r^(n+1))/(1-r)
2(1-2^(15+1))/(1-(1/4))
about 2 and 2/3, so closer to 3
My answer is 57 times .....
plse mark me the brainliest
Hey there,
3.5 L = 3.5 x 1000
= 3,500 mL
The second bottle has more water than the first bottle,
3,750 mL - 3,500 mL = 250 mL
Hope this helps :))
