    First, lets find the common ration between the first 3 terms.

    50 / 10 = 5

    250 / 50 = 5

    Second, multiply the common ration to each term to find the next term.

    First term: 10

    Second term: 10 * 5 = 50

    Third term: 50 * 5 = 250

    Fourth term: 250 * 5 = 1,250

    Fifth term: 1,250 * 5 = 6,250

    Sixth term: 6,250 * 5 = 31,250

    Seventh term: 31,250 * 5 = 156,250

    Eigth term: 156,250 * 5 = 781,250

    Thus, the 8th term of the geometric sequence is 781,250

    Best of Luck!

    Answer: 781,250

    Step-by-step explanation: Begin by studying the pattern.

    Here, notice that 10 * 5 is equal to 50.

    In the same way, 50 * 5 is equal to 250.

    Continuing the same pattern, 250 * 5 is equal to 1,250.

    1,250 * 5 is equal to 6,250.

    6,250 * 5 is equal to 31,250.

    31,250 * 5 is equal to 156,250.

    156,250 * 5 is equal to 781,250.

    This means that the 8th term in this pattern is 781,250.
