Answer :
The 23rd term in the sequence 163, 159, 155, 151, ... is 75.
An arithmetic sequence is a sequence of numbers where the difference between any two consecutive terms is constant. This means that you can find any term in the sequence by adding the common difference to the previous term.
The general formula for an arithmetic sequence is:
a_n = a_1 + d(n - 1)

where:
a_n is the nth term in the sequence
a_1 is the first term in the sequence
d is the common difference
n is the number of the term
The sequence is a decreasing arithmetic sequence, which means that each term is less than the previous term by a constant amount. In this case, the constant amount is 4. This is a decreasing arithmetic sequence, where each term is 4 less than the previous term. The first term is 163, so the 23rd term will be 163 - 4 * 22 = 75.
