Answer:
an=a1+d(n−1) a n = a 1 + d ( n - 1 )
Step-by-step explanation:
This is an arithmetic sequence since there is a common difference between each term. In this case, adding −5 to the previous term in the sequence gives the next term. In other words, an=a1+d(n−1) a n = a 1 + d ( n - 1 ) .
Answer:
≥ and ≤ will both be solid dots, as it includes the number
