Determine the value of D and A10 for each arithmetic sequence:
1. 3,5,7,9,...
2. -3,-6,-9,-12,...
3. 2, 1 ,1, ,...
Find the value of x, then write the first 5 terms of the arithmetic sequence, given a1 and d:
1. a=x, d=3x, a=25
2. a=x, d=x, a=10
3. a=x, d=, a= -11.5
Solve each problem:
1. Find the 23rd term of the sequence 5.7, 3.6, 1.5,...
2. If the 3rd term of an arithmetic sequence is 13 and the 9th term is 37, what is the common difference?
3. If the arithmetic sequence is 11 and the term is -77, what is the 20th term?
4. The last term of an arithmetic sequence is -104, the common difference is -13, and the number of terms is 13. What is the first term?
I know it might be long but I need the answers for 3 days but you can send it later if you want, tysm for helping me
