    Averigua el término siguiente en cada una de las sucesiones: a) -3, -5, -7, -9, ________ b) 5, -10, 20, -40, ________

    Correct Answer
    11
    80
    Explanation
    The given sequences are arithmetic sequences with a common difference of -2 in the first sequence and a common ratio of -2 in the second sequence. In the first sequence, each term is obtained by subtracting 2 from the previous term. Therefore, the next term is obtained by subtracting 2 from the last term, which is -9. Hence, the next term is -11. In the second sequence, each term is obtained by multiplying the previous term by -2. Therefore, the next term is obtained by multiplying -40 by -2, which is 80.

    El 21° numero de la sucesion 4,9,14,19,24...es:

    • C.

      103

    • D.

      105

    Correct Answer
    A. 104
    Explanation
    The given sequence starts with 4 and increments by 5 each time. So, the next number in the sequence would be 24 + 5 = 29. The 21st number in the sequence would be 4 + (20 * 5) = 104. Therefore, the correct answer is 104.
