The common difference is 3.
So the slope is 3.
-----
You have y-values for x = 1,2,3,4,5.
If x was 0, y would be 2-3 = -1
That is the y-intercept.

Your equation:
y = 3x-1

if I match up the x and y values, I see
+y%5Bn%5D+-+x%5Bn%5D+=+x%5B2n-1%5D+
+y%5Bn%5D+=+x%5Bn%5D+%2B+x%5B2n-1%5D+
check:
+y%5B5%5D+=+x%5B5%5D+%2B+x%5B2%2A5-1%5D+
+y%5B5%5D+=+x%5B5%5D+%2B+x%5B9%5D+
+14+=+5+%2B+9+
+14+=+14+
OK

I'm not sure if this is what they are looking for.
You might want a 2nd opinion.
