Find the nth term

Question 1

For the sequence 3, 5, 7, 9

The n^th term is 1 + 2n

If n = 10, find the 10^th term

Answer 1

1 + 2(10) = 1 + 20

= 21

Question 2

For the sequence 3, 5, 7, 9

The n^th term is 1 + 2n

If n = 100, find the 100^th term

Answer 2

1 + 2(100) = 1 + 200

= 201

Question 3

For the sequence 4, 7, 10, 13

The n^th term is 1 + 3n

If n = 10, find the 10^th term

Answer 3

1 + 3(10) = 1 + 30

= 31

Question 4

For the sequence 4, 7, 10, 13

The n^th term is 1 + 3n

If n = 100, find the 100^th term

Answer 4

1 + 3(10) = 1 + 300

= 301

Question 5

For the sequence 10, 8, 6, 4

The n^th term is 12 - 2n

If n = 10, find the 10^th term

Answer 5

12 - 2(10) = 12 - 20

= -8

Question 6

For the sequence 10, 8, 6, 4

The n^th term is 12 - 2n

If n = 100, find the 100^th term

Answer 6

12 - 2(100) = 12 - 200

= -188

Question 7

For the sequence 10, 7, 4, 1

The n^th term is 13 - 3n

If n = 10, find the 10^th term

Answer 7

13 - 3(10) = 13 - 30

= -17

Question 8

For the sequence 10, 7, 4, 1

The n^th term is 13 - 3n

If n = 100, find the 100^th term

Answer 8

13 - 3(100) = 13 - 300

= -287
