    Answer:

    see explanation

    Step-by-step explanation:

    Given the sequence

    1, 4, 9, 16, ….

    has n th term

    [tex]a_{n}[/tex] = n²

    (a)

    Given the sequence 2, 5, 10, 17, ……

    Note the terms are 1 more than the previous given sequence, thus

    [tex]a_{n}[/tex] = n² + 1

    (b)

    Given 2, 8, 18, 32, ……

    Note the terms are twice the original given sequence, thus

    [tex]a_{n}[/tex] = 2n²
