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
Starting with the number 4, applying the rule of multiplying by 2 and then subtracting 3 gives the following sequence: 4, 5, 7, 11, 19, 35. This pattern can be calculated as follows: 4 x 2 - 3 = 5, 5 x 2 - 3 = 7, 7 x 2 - 3 = 11, 11 x 2 - 3 = 19, 19 x 2 - 3 = 35.
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
Everytime you move to the next number you add 1, then 2, then 3, etc.1+1=22+2=44+3=77+4=1111+5=1616+6=2222+7=2929+8=37
