1. The problem gives a sequence with some missing terms and a term-to-term rule: subtract 12. 2. The known terms are the 2nd term = 23 and the 3rd term = 11. 3. Since each term is 12 less than the previous term, we can find the 1st term by adding 12 to the 2nd term: $$\text{1st term} = 23 + 12 = 35$$ 4. To find the 4th term, subtract 12 from the 3rd term: $$\text{4th term} = 11 - 12 = -1$$ 5. To find the 5th term, subtract 12 from the 4th term: $$\text{5th term} = -1 - 12 = -13$$ 6. The complete sequence is: $$35, 23, 11, -1, -13$$
