2. Answer:

   5.

   Step-by-step explanation:

   When you arrange the observations in. ascending order then you get,

   2,5,5,a,8,8,9

   we know mode is the observations which repeats most no. of times. Here 5 and 8 are equal in repetition but when anyone of the observation is increased by one more time, it will become the mode of these observations. And given that 5 is mode which means it repeats one more time than that of 8 so a is 5.
