If you subtract the first number and the second number, you obtain:
If you subtract the second number and the second number, you obtain:
Therefore, you must subtract and
to obtain the number asked. Then, this is:
The 15th term of the arithmetic sequence
Option B is correct
The nth term of an arithmetic sequence is given as:
The first value, a = 22
Since
The common difference, d = 3
The 15th term of the arithmetic sequence = 64
