Number pattern help.......?

Question

kindly give the rule for solving this number pattern.

3,6,10,15......

and

1,1,2,3,5....

Answer 1

for the first one you just add another number

3,6 is 3

6,10 is 4

10, 15 is 5

so the next number is

15,21   you add 6

21, 28 you add 7 and so on.

dont know about the second one. I have an idea but dont want you to get it wrong.

Answer 2

1) each successive number is sum of the previous number and one more the difference between the previous 2 numbers; 15-10= 5     15+(5+1) =21 next number is 21

2) each successive number is sum of previous 2 numbers , this is fabonacci sequence and it is recursive meaning it depends on terms before it to get next terms

next number is 3+5 = 8

hope this helps
