Calculate a57 for the sequence
daser333 [38]

Answer:

A) 78

Step-by-step explanation:

The given sequence is an arithmetic sequence.

Here A1 = -6, common difference = (3/2)

nth term An = a1 + (n -1)d

A57 = -6 + (57 -1)3/2

= -6 + (56)*3/2

= -6 + 28*3

= -6 + 84

A57 = 78

Thank you.

Which of the following sets would have a graph with an open circle on 2 and a ray pointing left on the number line?
MaRussiya [10]
Hi, the graph you describe represents all real numbers smaller than 2, without the two (that's why there's the open circle). Hence the correct answer is the third choice <span>{x | x ∈ R, x < 2}.

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!
