Just keep on trying, the answer will come up, my algorithm was something like this
create a "cumulative" variable and set it equal to user input "a"
Inside the INPUT FOR Loop
1)Create a new for loop for a variable say "j", start it from 0 to n where n is the input provided by user and already written in the code.
2)compute the part of (2^j)*b and store it in a variable say "res".
3) Now simply add the equation to the cumulative variable -> cumulative=cumulative+res(refer step 2)
4) Print (cumulative+" ")
5) Close for loop
6) user proper Println syntax tomove cursor to next line.

i mean first you have to calculate the first term then see that the first term is common in all terms so you have to just appy a loop after that , and in that loop i have told that what we have to perform. Now just simply iterate that loop and multilpy that first term to the matter that you calculated inside the loop.

it's a simple ques. you just need to print the series. look at series.. scan num=a and add 2^n.b and print.. as simple.

how i can increment the number 'n' value for getting the series, i dont know how to put loop for this, can anyone plz help me

same with me

but it doesn't pass through all the test cases.
