How do i do the ff. [Arithmetic Sequence]?

Question

Homework help , can you show me how to do them please ?

How do i form the first five terms of

1.a1= 0, d=3

2.a1 =8, d=6

3.a1=1/4th ,d= 1/3rd

4.a1 = 3[Square Root]2 ,d = 2[square root]2

Finding the indicated term.

5 2,6,10,...(a9)

6.18,15,12,...(a20)

7.-5, -4 and 1/2 , -4,...(a17)

8.2.3,4.4,5.6,...(a12)

Problem solving

9.if the fourth term of an arithmetic sequence is 15 and the eighth term is 7 write the first three terms



10.find the common difference of an arithmitic sequence of 33 terms if the 1st term is -3 and the last term is 5

The first five terms of an arithmetic sequence are
a, a+d, a+2d, a+3d, a+4d.
In general, the nth term is a+(n-1)d.

1. 0, 3,6,9,12
2. 8,14,20,26,32
3. 1/4, 7/12,11/12,5/4,19/12
4. 3sqrt(2), 5sqrt(2), 7sqrt(2), 9sqrt(2), 11sqrt(2)
5. a=2, d=4, a9 = 34
6. a=18, d=-3, a20=-39
7. a=-5, d=0.5, a17 = 3
8. a=3.2, [assume typo] , d=1.2, a12=16.4
9. 4d= -8, d= -2, so first three terms are 21,19,17
10. 32d=5-(-3)=8, d=0.25
