  1. Sep 8, 2005 #1
    List the first 10 trems of each of these sequences.

    i need help with this one:
    1.) the sequence whose nth term is the sum of the first n positive integers

    1,2,3,6,12,24,48,96....

    i'm not really sure if this is correct. what im doing is just adding the previous numbers together to get an answer.

    "the sequence whose nth term is the sum of the first n positive integers"
    So for n = 1, add the first 'one' integers: 1
    For n = 2, add the first two integers: 1+2 = 3
    For n = 3, add the first three integers: 1+2+3 = 6
    ...
