ANSWER

The second term is 7.

EXPLANATION

The given sequence has it's first term to be:

$t_1 = 3$

The recursive definition is :

$t_{n+1}=2t_n+n$

To find the second term , we substitute n=1,

to obtain,

$t_{1+1}=2t_1+1$

This implies that:

$t_{2}=2t_1+1$

$t_{2}=2(3)+1$

Simplify:

$t_{2}=6+1$

$t_{2} = 7$

During a football game a concert in stenciled family three hamburgers and two white dogs for a total of $13 and another family t

Answer:

Price of hamburgers = $2

Price of white-dogs = $3

Step-by-step explanation:

Let

The number price of hamburgers be x

The number price of white-dogs be y

Then the first family buys 3 hamburgers and 2 white -dogs for $13

3x + 2y = 13-----------------------------(1)

Another first family buys 2 hamburgers and 5 white -dogs for $16

2x + 5y = 16----------------------------(2)

To solve let us multiply eq(1) by 2 and eq(2) by 3, we get

6x + 4y = 26-----------------------------(3)

6x + 15y = 48----------------------------(4)

subracting (3) from (4)

6x + 15y = 48

6x + 4y = 26

(-)

-------------------------

11y = 22

---------------------------

$y =\frac{22}{11}$

y =2

Now substituting the value of y in eq(1),

3x + 2(2) = 13

3x + 4 = 13

3x = 13-4

3x = 9

x = $\frac{9}{3}$

x =3
