1. What must be the value of k so that 5k-3, k+2, and 3k-11 will form an arithmetic sequence?

2. which term of the arithmetic sequence whose first term is -3,common difference is 2, and last term is 23?

3. find a sub 1 if a sub 8=54 and a sub 9=60.

4. find the 9th term of the arithmetic sequence with asub1 =10 and d= -1/2

5. give the arithmetic sequence of 5 terms if the first term is 8 and the last term is 100.
