What conjecture can you make about the sum of the first 29 positive even ​numbers?

Mathematics

An = A1 + (N-1)d 
A1 is the first term (in this case 2)
d is the common difference (what is the difference between all consecutive even numbers? 2)
N is the number of terms to find (in this case 29)
An = 2 + (29-1)2 = 58
I would say none of the above, unless you typed it wrong.  The sum is the product of the number of terms minus one and two, plus two more.  So it's almost answer B but not really.  Good luck with this one.

y-intercept: find the one point on the graph that is exactly on the y-axis.
