    Given the value of t3 and t7, and t7 = t3 * r^4, where r represents the geometric quotient.

    So 7104 = 444 * r^4 - > solve for r, you will get r = 2 or - 2

    So, for r = 2, t6 = t7 / r = 7104 / 2 = 3552

    For r = - 2, t6 = - 3552

    If we divide the 7th term by the third it gives us r^4 (common ratio to power 4).

    r^4 = 7104/444 = 16

    so r = 4th root of 16 = 2

    So 6th term will be the 7th term / 2 = 7104 / 2 = 3552
