Assignment Due April 19th

This assignment deals with the solving of patterns. In order to answer this assignment you need to respond to this post with a comment.

For each pattern you need to tell me what is the pattern, and what the next three missing numbers are in the pattern.

Example: 1, 2, 4, 8,16, _, _, _ The pattern starts at 1, with each new number double the last number.

Pattern #1: 2, 5, 8, 11, 14, _, _, _,

Pattern #2: 99, 89, 79, _, _, _

Pattern #3: 1, 4, 9, 16, _, _, _

Pattern#4: 1, 1, 2, 3, 5, 8, 13, 21, _, _, _

Happy puzzle hunting.

Bonus Mark. The fourth pattern is a very special and very unique pattern that is found commonly in nature. For one additional mark tell me the name of this pattern.

    Thank You Mr. Reece, this was fun. I probably got them all wrong, but I was wondering what the answer to the bonus is.

  • Pattern #1: You add 3 to the number. The next 3 numbers are 17, 20, 23

    Pattern #2: Minus 10 from the number. The next 3 numbers are 69, 59, 49.

    Pattern #3: Count the odd numbers and add them to the next number. Example: Counting odd numbers like 1, 3, 5, 7, 9. Add each number to the next number. So say u add 1 to the number 3. That gives you 4. Then add the next odd number 3 to 3 and that gives you 9. Add 5 to the number 9 and that gives you 14. The next 3 numbers are 25, 36, 49.

    Pattern #4: The pattern is adding the number to the next number. Example on the question is 1 + 1 = 2. 2 + 3 = 5 and so on. The next 3 numbers are 34, 55, 89.

  • 1) pattern starts at 2, and increases by 3 on each new number. the next numbers are: 17, 20, 23

    2)pattern starts at 99 and subtracts 10 on each new number. the next 3 numbers are 69, 59, 49

    3)pattern starts at 1, increases by 3, then 5, then 7 so the number it increases by increases itself by 2 each time. the next numbers are 25, 36, and 49

    4)pattern starts at 1 with each new number increasing by the amount of the number before. the next numbers are 34, 55, and 76
    (got no clue about the type of pattern but i'll guess: pattern dipped in nuclear waste? hahahaha)

  • Pattern #1
    17, 20 and 23
    The pattern is simply adding 3.

    Pattern #2
    69, 59 and 49
    The pattern is simply minus 11.

    Pattern#3
    25, 36 and 49
    The pattern is simply adding 2 more to equal the next number.

    Pattern #4
    34, 55, and 89.

    Well thats all for now
