Hey there! :)
The lowest number is 72. The greatest is 98. The intervals are by 5. Find the difference between 72 and 95 and divide by 5. If there is a remainder, add 2 to the whole number.
98 - 72 = 26
26 ÷ 5 = 5.2
The whole number is 5. If you leave it 5.2, that won't be an interval. That's why you add 1. 5 + 1 = 6
Remember that you din't start from 1. You started from 72. Add an interval from 1 - 72 and leave it empty.
6 + 1 = 7
Answer ⇒ 7
