Answer: The number that was removed was Ten--- d

Step-by-step explanation:

Step 1

Mean = Sum of integers/ number of integers

30 = X / 6

Sum of the integers= 180

Step 2

Let n be the number that was removed , so that

Mean = Sum of integers/ number of integers sum  will now be written as

34=  180-n /  5

170 = 180-n

n = 180 -170

n= 10
