Question

For each of the following number sequence below,
1.state the first term , and write the next four terms of the sequence
2. Find the common difference
3.find the general Th for the sequence
4.write down the input and output value of the five terms of the sequence in a table
5.represent the number sequence on a coordinate plane in a graphic form
6.write down the number sequence of positive multiples of three starting at six
7. 9;14,19;...
8. 3:7;11;....
9. 8;15;22;...
10. 4 ;11,18

Answer 1

$9,14,19,...$

common difference $d=5$

$a_n=9+5(n-1)$

$3,7,11,...$

$d=4$

$a_n=3+4(n-1)$

$8,15,22,...$

$d=7$

$a_n=8+7(n-1)$

$4,11,18,...$

$d=7$

$a_n=4+7(n-1)$

the number sequence of positive multiples of three starting at six:

$6,9,12,...$
