The point next visited will be (19,16)
Because:
When the numbers are the same the line is going diagonally upward, whereas if the numbers have a difference of one the line must be going diagonally downward-leading to our solution of (19,16)
40 points would be visited before the point (9,4)
Because:
The nearest triangle number (36)plus 4 is the answer because the points make a triangle at the end of each row and as our coordinates are mid row we wroked them out using 36+4. WE also checked our solutions by drawing out the diagram up to the required numbers.
