One rule for this pattern is to add twice the previous value added
4 + 1 = 5
5 + 2×1 = 5 + 2 = 7
7 + 2×2 = 7 + 4 = 11
11 + 2×4 = 11 + 8 = 19
Continuing the next numbers would be:
19 + 2×8 = 19 + 16 = 35
35 + 2×16 = 35 + 32 = 67
...
3+4= 7 7+4=11 11+4= 15 15+4=19 19+4=23 23+4=27 27+4=31
multiply by 5 add 4
67 7 + 4 = 11 11 + 8 = 19 19 + 16 = 35 35 + 32 = 67 67 + 64 = 131 ...
the rule is add 7 because 4 plus 7 = 11
Term 1: 4 Term 2: 4 x 2 - 3 = 5 Term 3: 5 x 2 - 3 = 7 Term 4: 7 x 2 - 3 = 11 Term 5: 11 x 2 - 3 = 19 Term 6: 19 x 2 - 3 = 35
The pattern will be +2, +3, +4, +4
Add 3 each time
3+4= 7 7+4=11 11+4= 15 15+4=19 19+4=23 23+4=27 27+4=31
from 12 to 16 is 4 then from 16 to fiftine is one then from15-19 is 4 so one so forth one is +4 the next is -1
19 + 3 = 22 to repeat the pattern
multiply by 5 add 4
67 7 + 4 = 11 11 + 8 = 19 19 + 16 = 35 35 + 32 = 67 67 + 64 = 131 ...
Do you mean: (-4, -11) and (-18, -19) Then the slope is: (-11--19)/(-4--18) = 4/7
The rule is multiply the previous term by -1 to find the next term.
Do you mean: (-4, -11) and (-18, -19) Then the slope is: (-11--19)/(-4--18) = 4/7
the rule is add 7 because 4 plus 7 = 11
For a linear sequence (same differences) look for the difference first. E.g.7, 11, 15, 19 ...This has a difference of 4 so the first part of the rule is 4n. (the rule follows the 4 times table)Now compare the sequence to the 4 times table7, 11, 15, 19 ...4, 8, 12, 16 ...Out sequence is always 3 larger than the four times table so we adjust our rule by adding 3. So our final rule is 4n + 3.
