Hint: All those 1's and 5's. Does this remind you of other symbols?
Hint: Other symbols that might be part of a number system?
Hint: An ancient numbering system that used letters?
Solution: The numbers are the values of the Roman numeral symbols, in order from 4 through 8. The next two numbers, 1 and 10, would represent 9.
1-5...5...5-1...5-1-1...5-1-1-1...1-10 IV....V...VI....VII......VIII.....IX 4....5...6......7........8.......9
The next number is 13, the total of the two numbers preceding it.
You add the last two numbers together to get the next number, and 3+5=8, so the answer is 8!
what would be the next two numbers in this pattern 5 -30 180 -1080
The next number is 13... you're adding the previous two numbers together to produce the next in line.
13, 21 - it is the Fibonacci sequence
55 and 89
That's the Fibonacci sequence! XD They're 21 and 34 if you add up the last two numbers to get the next one.
23. The pattern is simply add the previous two numbers to find the next one.
The pattern seems to be +10 then -5. Therefore the next two numbers would be 26 and 36.
The two numbers are 6 and -5. 6 x (-5) = -30, 6 + (-5) = 1.
That's a Fibonacci sequence. After the first two numbers, each new number is the sum of the previous two numbers. The next number in that sequence would be 13.
what are the next numbers in the pattern 1, 2, 3, 5, 8, 13,_,_
