Answer:
45, 56, 67
Explanation:
Terms of an arithmetic sequence have a common difference. That is, the next term is found by adding that difference to the previous term.
Here, the difference is 12 -1 = 11, so each term is 11 more that the previous one. The next terms are found by repeatedly adding 11.
34 + 11 = 45
45 + 11 = 56
56 + 11 = 67
The next three terms are 45, 56, 67.
