    Continuing Patterns in Sequences... please help

    Hey everyone, I need to find patterns and continue each sequence to the next two numbers in the sequence. I was able to solve most of them but here are the 5 I'm completely stuck on... I'd appreciate any help. Thanks

    1,4,9,16,27,_,_
    1,1,1,3,5,9,17,_,_
    0,5,8,8,2,3,5,2,9,4,_,_
    10,40,90,61,52,63,94,_,_
    2,7,1,8,2,8,1,8,2,8,4,5,_,_

    Thanks again for any help

    Hello, WzMath16!

    I got a few of them . . .


    2)\;\;1,\,1,\,1,\,3,\,5,\,9,\,17,\,\hdots
    The sequence begins with 1, 1, 1.

    Each subsequent term is the sum of the preceding three numbers.

    The next two terms are: . 5+9+17 \:=\:31 and 9 + 17 + 31 \:=\:57



    4)\;\;10,\,40,\,90,\,61,\,52,\,63,\,94,\,\hdots
    Reverse the numbers: .  01,\:04,\:09,\;16,\;25,\;36,\;49,\;\hdots

    Got it?



    5)\;\;2,\,7,\,1,\,8,\,2,\,8,\,1,\,8,\,2,\,8,\,4,\,  5,\,\hdots
    These are the digits of the number e\:=\:2.718281828459045\hdots
