Después de ver todos los análisis y no entenderlos, he llegado a la siguiente conclusión y no me parece descabellada:
1ra serie: 4 5 7 11 19 35 67
relación: +1+2 +4 +8 +16 +32
nexo de la relación: multiplicar por 2, o sea, 21=2/22=4/42=8/82=16/16*2=32
por tanto sería:
Espero se entienda. Saludos Nilda
n0 = 4
n1 = (n0-2) + (n0-1) = 2 + 3 = 5
n2 = (n1-2) + (n1-1) = 3 + 4 = 7
...
ni = (n - 2) + (n -1)
4+1=5
5+2=7
7+4=11
11+8=19
19+16=35
35+32=67
67+64=131
4-5 difference is 1
5-7 is 2
7-11 is 4
11-19 is 8
etc
The difference is multiplied by 2 each time and added to the larger number
I have no idea the answers here are : 198 163 141 3 167
I'm
67 7 + 4 = 11 11 + 8 = 19 19 + 16 = 35 35 + 32 = 67 67 + 64 = 131 ...
The answer is 67 because the pattern is 2x(x-1)-3 11-7 is 4 19-11 is 8 which is twice 4 35-19 is 16 which is twice 8 so the next difference is twice 16, =32 so the next number is 35+32 =67
67
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 ...
67
67 7 + 4 = 11 11 + 8 = 19 19 + 16 = 35 35 + 32 = 67 67 + 64 = 131 ...
7+4=11 11+8=19 19+16=35 35+32=67 so the next no. is 67..............

11 - 7 = 4 19 - 11 = 8 35 - 19 = 16 67 - 35 = 32 Getting the picture? Just double the amount added on the previous one.
The next number in the series is 67.
Note the difference between each pair is doubled compared to the previous pair. 5 ; 7 = 2^1 7 ; 11 = 2^2 11 : 19 = 2^3 19 : 35 = 2^4 So 35 : x = 2^5 = 32 So 35 + 32 = 67 .
The answer is 67 because the pattern is 2x(x-1)-3 11-7 is 4 19-11 is 8 which is twice 4 35-19 is 16 which is twice 8 so the next difference is twice 16, =32 so the next number is 35+32 =67
67
7 11 19 35 67 131 259 515... Double the last number then take away 3 for the next number.
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 ...
67
Assuming I got it right 67
