Question

*What is the 8th term of the sequence given by a n=3n-5 ?

-2
19
24
29

*write a recursive definition for the sequence below
-1,4,9,14

*write an explicit formula for the sequence 2,8,14,20,26

a n=2n-2
a n=2n+2
a n=4n+2
a n=6n-4

Answer 1

1. 8th term = 3×8 -5 = 19
2. An = -1+5(n-1)
3. An = 6n -4

Answer 2

1. 19

2.
`a_(1)=-1`;
`an=a_(n-1)+5`

3. an=6n-4
