Add 2.
The rule is (-2, -5)

That the last digit is 0. 2 4, 6 or 8.
rule 1: keep quiet rule 2: catch a fish rule 3: put the fish back rule 4: leave it's pointless
The rule is: Un = 2 - 2n for n = 1, 2, 3, ...
y = 8 - 2*x
An example of a symbolic rule is y=2x-5. Since this is in the y=mx+b form, the y-intercept (b) is -5. If your rule looks different, e.g. 3x-2y+8=0, then put 0 in for x, and solve for y: 3(0) -2y +8 = 0 <=> -2y +8 = 0 <=> -2y = -8 <=> y = -8/-2 <=> y=-4. 9 out of 10 teachers (I'm with them) would say that the y-intercept is the number -4. The other one would say it is the point (0,-4)
x1=0 x2=1 for i > 2, xi= xi-1 + xi-2
The next number is 12. The rule is Un = (2n4 - 27n3 + 123n2 - 214n + 120)/2 for n = 1, 2, 3, ...
One possible rule is Un = (-1493n3 + 13443n2 - 38890n + 36024)/6 for n = 1, 2, 3, 4.
