Answer:
the next term is term containing 15 dots
Step-by-step explanation:
first term = 1
2nd term = 3
third term = 6
fourth term = 10
watching the sequence closely we see that for the next number is as a result of adding the next number from the numbers (1,2,3,4,5,6,7...)
so the number 0 was added 1 to give 1
the number 1 was added 2 to give 3
the number 3 was added 3 to give 6
the number 6 was added 4 to give 10
the number 10 will be added 5 to give 15
so the new arrangement is 15 dots arrangement with 5 dots below, following it is 4 dots, then 3 dots, then 2 then 1 adding up to 15
