Answer:

T_n = -5 -2(n-1) = -3 - 2n

Explanation:

This is an arithmetic sequence with a common difference of -2 (-5 -2 = -7, -7 - 2 = -9, -9 -2 = -11 ...)

so, T_n = -5 -2(n-1) = -3 -2n

we use -5 as the starting point because that's the first term. whether you simplify or not depends on you and your teacher.
