Find 3 values equal and consecutive in the row of a matrix.

Goodnight. Disturbing them again with another concern. I have a matrix called "Cons" that in its last row is numbered (which is not necessarily ascending or has a consecutive order, like 1,2,3 ... etc). I want to look for groups of 3 elements (in that row) that are equal and consecutive, so that I can indicate the positions of these groups. It should be noted that the "Cons" matrix is of variable size, and therefore the length of its last row depends on the size of the first. The variable "i" indicates the position of the last row. Below I leave an image to better illustrate the matter
Thank you very much to all.
