How do you put 245 -137 on a number line

Start at 100 and use intervals of 20 to go up in the number line
like this
100120--140--160--180--200--220---240--260-
and then input the values 137 and 245 on the number line like this
100--120--137-140--160--180--200--220--240-247--260

Ican’t answer if there is no diagram
