Answer:
a₅₂ = - 212
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 = - 8 and d = a₂ - a₁ = - 12 - (- 8) = - 12 + 8 = - 4 , then
a₅₂ = - 8 + (51 × - 4) = - 8 - 204 = - 212
In general it's not "good math" to write "+-". One way to rewrite 300+-50+-75+225 more clearly would be 300 - 50 - 75 + 225.
Working from left to right, 250 - 75 + 225
175 + 225 = 400 (answer)
