Final answer:
The given sequence is arithmetic with a common difference of 7. The explicit rule for the sequence is: an = a1 + (n-1)d.
Step-by-step explanation:
The given sequence: 1, 8, 15, 22, 29, ....
a. The common difference (d) between consecutive terms is 7. (d = 7)
b. The first term (a1) is 1. (a1 = 1)
c. The zeroth term (a0) is not given.
d. The sequence is arithmetic because the difference between consecutive terms is constant.
f. The explicit rule for the sequence is: an = a1 + (n-1)d, where an represents the nth term, a1 is the first term, and d is the common difference.
