    The sequence described by given explicit formula is: -4,-1,4,11,20,….

    Step-by-step explanation:

    Given explicit definition is:

    a_n = n^2-5

    We will put n=1,2,3,…. to determine the sequence

    So,

    Putting n=1

    a_1 = (1)^2-5\\=1-5\\=-4

    Putting n=2

    a_2 = (2)^2-5\\=4-5\\=-1

    Putting n=3

    a_3 = (3)^2-5\\=9-5\\=4

    Putting n=4

    a_4 = (4)^2-5\\=16-5\\=11

    Hence,

    The sequence described by given explicit formula is: -4,-1,4,11,20,….
