Question

HELPP PLEASE IM ACTUALLY STUCK???

Answer 1

`d=-8`

Explanation:

If the first term of a sequence is
`258` and the second term is
`250`, then each successive term in the sequence is
`8` less than the previous term. Therefore, the common difference is
`-8` (
`d=-8` ).

The formula representing the arithmetic sequence is:

`a_n=-8n+266`

Therefore:

Term 1:
`a_1=-8(1)+266=-8+266=258`

Term 2:
`a_2=-8(2)+266=-16+266=250`

Term 3:
`a_3=-8(3)+266=-24+266=242`

…

Term 9:
`a_9=-8(9)+266=-72+266=194`
