2,9,20,35,54,77
What's this pattern
What's the next 3 sequence

Sequence=104 135 170
Pattern= when subtracting 9 from 2 you get 7, when subtracting 20 from 9 you get 11. The difference between 11 and 7 is 4. 7+4=11 so the number will go up 11 times, then adding 4 to 11 you will get 15 so the next number will go up 15 times.
Ex 1. 20,35
35-20=15
(15-11=4)
20+15=35

Ex 2. 35,54
54-35=19
(19-15=4)
35+19=54
Tbh I never heard of sequence but I tried my best to explain how I got my answer sorry if it’s confusing ask me anything if you don’t understand it

We have that for the Question ,it can be said that the next 3 sequence is

104135 170

Respectively

Generally

We notice that the difference between numbers in the sequence rises by 4

therefore

For the first differ

9-2=7

7+4=11

Hence

11+9=20

Generally

for the sixth value

4*5=20

20+7=27

27+77=104

Therefore

the next 3 sequence is

104135 170

Respectively
