creativ13 [48]

Answer:

The first 5 terms of the sequence is 2,7,15,26,40.

Step-by-step explanation:

Given : Consider the sequence defined recursively by $a_0=0$ $a_n=a_{n-1}+3n-1$

To find : Write out the first 5 terms of this sequence ?

Solution :

$a_n=a_{n-1}+3n-1$ and $a_0=0$

The first five terms in the sequence is at n=1,2,3,4,5

For n=1,

$a_1=a_{1-1}+3(1)-1$

$a_1=a_{0}+3-1$

$a_1=0+2$

$a_1=2$

For n=2,

$a_2=a_{2-1}+3(2)-1$

$a_2=a_{1}+6-1$

$a_2=2+5$

$a_2=7$

For n=3,

$a_3=a_{3-1}+3(3)-1$

$a_3=a_{2}+9-1$

$a_3=7+8$

$a_3=15$

For n=4,

$a_4=a_{4-1}+3(4)-1$

$a_4=a_{3}+12-1$

$a_4=15+11$

$a_4=26$

For n=5,

$a_5=a_{5-1}+3(5)-1$

$a_5=a_{4}+15-1$

$a_5=26+14$

$a_5=40$

The first 5 terms of the sequence is 2,7,15,26,40.

Answer pls in standard form too

romanna [79]

Answer:

Slope form y=2x+3

Standard form 2x-y=-3

Slope y=3/5x-6

Standard 3x-5y=30

slope y=-3/2x+9

standard 3x+2y=18

slope y=-3x+0

standard = 3x+y=0

Step-by-step explanation:

Slope form y=2x+3

Standard form 2x-y=-3

Slope y=3/5x-6

Standard 3x-5y=30

slope y=-3/2x+9

standard 3x+2y=18

slope y=-3x+0

standard = 3x+y=0
