(15 Points) Indicate the general rule for the arithmetic sequence with a3 = -4 and a8 = -29.

Step-by-step explanation:

= - 4

= a* + (3- 1) d*

- 4 = a + 2d . . . . . . . . .(i)

= - 29

= a + ( 8 - 1) d

- 29 = a + 7d . . . . . . . . (ii)

subtracting equations (i) and (ii)

25 = 5d

d = -5

placing d = -5 in equation (i)

a - 10 = -4

a = 6

For an arithmetic Progtession

= a + (n - 1)d

= 6 + (n- 1)-5

= 6 - 5n + 5

this is false ^.^ lol
