Hello,

1)
$a_{1}=7$
$a_{2}=7*3$
$a_{3}=7*3^2$

$a_{n}=7*3^{n-1}$

$s=a_{1}+a_{2}+a_{3}+a_{4}+a_{5}=7*(1+3^1+3^2+3^3+3^4)$
$=7*\frac{3^{5}-1}{3-1}$
$=7*242/2=847$

Can someone please help.

zvonat [6]

Answer:

8 jars

Step-by-step explanation:

Let the number of jars is x.

80 liters distributed, each jar has:

80/x

Redistribution with 4 less jars, each jar now has:

80/(x - 4)

Each jar has now twice the amount:

80/x*2 = 80/(x - 4)
2/x = 1/(x - 4)
2(x - 4) = x
2x - 8 = x
x = 8

She prepared 8 jars at the start
