Abe has a bag of marbles and wants to divide them into sets. The first set will have 2 marbles; the second set, 5; the third set, 8; the fourth set, 11; and so on. How many sets will he have if he starts with 40 marbles?

Respuesta :

Ok so the numbers are in a sequence of +3 so he would go 2,5,8,11,14. He could only have 5 groups of marbles because 2+5+8+11+14=40
