Answer:

12 - 2n

Step-by-step explanation:

The n th term of an arithmetic sequence is

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 10 and d = 8 - 10 = - 2, thus

$a_{n}$ = 10 - 2(n - 1) = 10 - 2n + 2 = 12 - 2n

What’s a problem with no solution

Free_Kalibri [48]

When a problem has no solution you'll end up with a statement that's false. For example: 0=1 This is false because we know zero can't equal one. Therefore we can conclude that the problem has no solution.
