This is an arithmetic sequence with t1 = 1 and the common difference d = -18.
The nth term of an arithmetic sequence is given by the formula:
tn = t1 + (n - 1)d (substitute 10 for n, 1 for t1, and -18 for d)
t10 = 1 + (10 - 1)(-18) = 1 + 9(-18) = 1 - 162 = -161
Thus the 10th number of the sequence is -161.
