Give the first five terms of the sequence given the nth term write the complete solution. 5. a_{n} = 11 + 7n
2. a_{n} = 2(n + 1)
4. a_{n} = 5 - n ^ 2
3. a_{n} = 3n - 5
1. a_{n} = n + 5

pahelp po. thanks! :)​

Answer:

1. 6,7,8,9,10

2. 4,6,8,10,12

3. -2,1,4,7,10

4. 4,1,-4,-11,-20

5. 18,25,32,39,46

Step-by-step explanation:

1. n+5

let n=1,2,3,4,5

then

1+5=6

2+5=7

3+5=8

4+5=9

5+5=10

2. 2(n+1)

let n=1,2,3,4,5

2(1+1)=2*2=4

2(2+1)=2*3=6

2(3+1)=2*4=8

2(4+1)=2*5=10

2(5+1)=2*6=12

3. 3n-5

let n=1,2,3,4,5

3*1-5=3-5=-2

3*2-5=6-5=1

3*3-5=9-5=4

3*4-5=12-5=7

3*5-5=15-5=10

4. 5-n^2

let n=1,2,3,4,5

5-1^2=5-1=4

5-2^2=5-4=1

5-3^2=5-9=-4

5-4^2=5-16=-11

5-5^2=5-25=-20

5. 11+7n

let n=1,2,3,4,5

11+7*1=11+7=18

11+7*2=11+14=25

11+7*3=11+21=32

11+7*4=11+28=39

11+7*5=11+35=46
