(1) the 18th tile in the row is not yellow. (2) the 19th tile in the row is not green.

Insufficient data.

Step-by-step explanation:

Given,

Green and red coloured tiles, every red tile is preceded immediately by a yellow tile and every yellow tile is preceded immediately by a green tile,

That is,

The order of tiles is,

Red(R), yellow(Y), green(G)

(1) if 18th tile is not yellow,

Then, possible 18th tile = red or green

Order      18            19           20             21            22          23          24

Tile        R/G          Y/R       G/Y            R/G          Y/R        G/Y         R/G,

(2) If 19th tile in the row is not green.

Then possible 19th tile = yellow or red,

Hence, the data is incomplete to tell what is the colour of 24th tile.
