Answer:
18
Step-by-step explanation:
mean of 10, 12, 13, x, 17 is 14
=> ( 10 + 12 + 13 + x + 17 ) / 5 = 14
=> 10 + 12 + 13 + x + 17 = 5 × 14 = 70
=> 52 + x = 70
=> x = 70 - 52 = 18

mean=sum of data/number of data
=> 14 = 10 + 12+ 13+ x + 17 / 5
=> (14×5=70) 14 = 52+x /5
=> 70 = 52+x and x=70-52=18
=> hence , the answer is 18
