1. The problem statement, all variables and given/known data
For the arithmetic sequence (2 - x),
(-6 + 2x), (x + 2), solve for x and find t10.
2. Relevant equations
an = a1 + (n - 1) d
3. The attempt at a solution
Would I have to start off like this below:::
an = a1 + (n - 1) d
d = (-6 + 2x)-(2 - x) = (x + 2)-(-6 + 2x)
