a. 4.2.10
b. 24. 20. 16
c. 55. 50. 45
d. 100. 150. 200
e. 980. 780. 680
f. 1200. 1150. 1100

Answer :

To solve the numeric patterns provided, we need to identify the rule or sequence governing each set of numbers. Let's analyze each part individually:

  1. 4, 2, 10:

    • This sequence might look tricky at first because the numbers seem unrelated. However, if we examine the sequence as operations between numbers, a possible pattern could be similar operations or a misinterpretation of the sequence, as numeric patterns usually have more terms. Without additional context or numbers, this sequence remains unclear.
  2. 24, 20, 16:

    • This is an arithmetic sequence where each number is decreased by 4.
    • To find the next number: 16 - 4 = [tex]12[/tex].
  3. 55, 50, 45:

    • This is an arithmetic sequence where each number is decreased by 5.
    • To find the next number: 45 - 5 = [tex]40[/tex].
  4. 100, 150, 200:

    • This sequence increases by 50 each time.
    • To find the next number: 200 + 50 = [tex]250[/tex].
  5. 980, 780, 680:

    • Here, the sequence decreases by 200 initially and then by 100.
    • If the pattern is to continue decreasing by the next hundred decrease: 680 - 100 = [tex]580[/tex].
  6. 1200, 1150, 1100:

    • This sequence decreases by 50 each time.
    • To find the next number: 1100 - 50 = [tex]1050[/tex].

In summary, while tackling numeric patterns, it's important to look for arithmetic operations such as addition or subtraction that occur consistently.
