Question

There are 4 semi-trailer trucks parked in a line at the rest stop. After the first truck, each truck in the line weighs 2 tons more than the truck before it. The trucks weigh a total of 32 tons. How many pounds does each truck weigh?

Answer 1

so we start off with what 4 numbers added together equal 32.
first truck 5 tons
second truck 7 tons
third truck 9 tons
and fourth truck 11.


`5 + 7 + 9 + 11`


5+7= 12 +9 = 21+11= 32.
