Number Frequency 140 145 150 155 160 165 170 What is the mode? 145 and 150 150 and 155 155 152

There is no mode. None of the numbers were repeated.

none, 150 and 155

Step-by-step explanation:

Mode from a set of values is the value which gets repeated the most.

Let us see the first part

140,145,150,155,160,165,170

In above set of values, no entry is being repeated. Hence there is no mode to above set of values.

Let us see the another set of values

145, 150, 150

in the above set, 150 gets repeated twice, hence the mode to the above set is 150

Let is see the third set of values

155,155,152

In the above set of entries, 155 get getting repeated, hence the mode will be 155.
