Answer:
a₂ = - 28.5
Step-by-step explanation:
the nth term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = - 45 and given a₃ = - 12 , then
a₁ + 2d = - 12 , that is
- 45 + 2d = - 12 ( add 45 to both sides )
2d = 33 ( divide both sides by 2 )
d = 16.5
Then
a₂ = a₁ + d = - 45 + 16.5 = - 28.5

Answer: yes
Step-by-step explanation: To determine whether <em>y = 7</em> is a solution to the inequality, substitute a 7 in for <em>y</em>.
So we have 17 > 2(7).
2(7) is 14.
So we have 17 > 14.
Since this is a true statement, then our answer is <em>yes</em><em>.</em>
7 is a solution to the inequality
