Describe the pattern in each sequence and determine the next term of the sequence

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
