B(n)=1 (-2)^n-1<br> What is the 4th term in the sequence
Vera_Pavlovna [14]

Answer:

The 4th term in the sequence is -8.

Step-by-step explanation:

The nth term of the sequence B is given by:

B(n) = (-2)^{n-1}

So the fourth term will be given by:

B when n = 4, that is, B(4).

B(4) = (-2)^{4-1} = (-2)^{3} = -8

The 4th term in the sequence is -8.

Elina [12.6K]

Answer:

<u>30 gallons solution 4% and 10 gallons solution 8%</u>

Step-by-step explanation:

<h3>x•4%+y•8%=40•5% </h3>

<em><u>4x+8y=40•5 and x+y=40</u></em>

x=40-y

4(40-y)+8y=200

160-4y+8y=200

4y=200-160

4y=40 => y=10 (gallons solution 8%)

=> x=40-10=30 (gallons solution 4%)

30 gallons solution 4% and 10 gallons solution 8%
