determine the next three numbers in this pattern:
2,3,5,7,11,13,17,19,23,___,___,___


Aren't these all prime numbers?


Find the next three numbers in the pattern. 5,2,-1,-4
3,2,0,-3,-7
-8,-6,-2,4,12
-5,-7,-8,-10,-11

  • math - ,

    The first pattern looks like all primes, so the next numbers in the sequence would be

    29, 31, 37

    ______________
    5, 2, -1, -4

    You subtract three to get the next number, so the next three numbers would be
    -7, -10, -13
    ______________
    3, 2, 0, -3, -7

    To get the second term, you subtract 1 (3-1 = 2)
    To get the third term, you subtract 2 from the 2nd term (2-2 = 0)
    . . . To get the (n+1)th term you subtract n-1 from the nth term

    The next numbers would be -12, -18, -25
    ______________________
    -8, -6, -2, 4, 12

    To get second term, you add 2 to the first term;
    To get the third term, you add 4 to the second term;
    To get the (n+1)th term, you add (n-1)*2 to the nth term
    The next terms in the sequence are
    12 + 8, 12 + 8 + 10, 12 + 8 + 10 + 12
    = 20, 30, 42

    __________________
    -5, -7, -8, -10, -11

    This looks like you alternating between adding -2 and -1; The next three terms would be

    -13, -14, -16
