Explanation
In Fibonacci, each number is the sum of the two previous; ५+३=८.
Lucas sequence next term is sum of previous two: ११+७=१८.
These are consecutive squares: 1^2,2^2,3^2,4^2,5^2,6^2,7^2.
Powers of two double each time: 2^0,2^1,....
Each term = sum of the previous three: 1+1+2=4, then 1+2+4=7, next 1+4+7=12? (Note: sequence shown uses 13 as next by standard Tribonacci variant)
Next prime after १३ is १७.
Sequence increases by 3 each step.
These are 3^0 through 3^6; next is 3^5=243.
Each term is sum of two previous: 11+18=29.
Each term doubles: multiply by 2.
