Hi friends, please help me with finding the rUle for these inputs aand outputs:
Inputs are 1; 3; 5 ;7 (X values)
Outputs are 5; 10; 15; 20 (Y values)
I did the following:
constant difference is according to the outputs, which is 5.
the formule used is y=bx+c, b equal to the constant difference
so we have y=5x+c.
So if I take the first term for example, to calculate "c"
y=5(x)+c
5=5(1)+c
c=0
however, using c=0, does not calculate correctly for the other terms. also, "c" calculates differently for each term. Please help, I really do appreciate.

xx+12(x+12)×511+12=11∗5=533+12=22∗5=1055+12=33∗5=1577+12=44∗5=20
The rule is y=(x+12)×5
Hi heureka,
Thank you for the response, however, could you kindly explain how you got to the rule in the first place...how did you know it had to be (x+1)2∗5
how you got to the rule in the first place:
Arithmetic progression: 1, 3, 5, 7, …
an=a1+(n−1)∗d|a1=1, d=2an=1+(n−1)∗2an=1+2n−2an=2n−12n=an+1n=an+12orn=x+12
