write a sequence for the rule a-4=b
To generate a sequence based on the rule a - 4 = b, we can start with an initial value for a and then subtract 4 from it to get the corresponding value of b.
Let's choose an initial value of a as 10. By substituting it into the given rule, we have 10 - 4 = b. Simplifying this, we find that b = 6.
So, the first term of our sequence is 6.
To generate the next term, we can use the same rule by taking the previous term and subtracting 4 from it. Thus, 6 - 4 = 2. So, the second term of our sequence is 2.
We can continue this process to generate more terms:
3rd term: 2 - 4 = -2
4th term: -2 - 4 = -6
5th term: -6 - 4 = -10
Therefore, the sequence based on the rule a - 4 = b, starting with a value of 10, is: 6, 2, -2, -6, -10, ...
