Yyyyyyyyyyyyyyyyyyyyyyyyyooooooooooooooooooooouuuuuuuuuuuurrrrrrrrrrrrr WELCOME
You know a1.
So find a2, a3, and so on until a7.
a(1) = 12
a(2) = 16
a(3) = 20
a(4) = 24
a(5) = 28
a(6) = 32
a(7) = 36
Each is 4 more than the previous.
Y+4=10(x+3)
Y+4=10x+30
Y=10x+26
I'd personally go with A and C, The rest don't make too much sense. Don't count on my answer just yet though.
The answer is 4.953 I don't understand how you would use a table sorry.
