Answer: The 18th term is 295.
Step-by-step explanation: By using the arithmetic sequence formula:
a(n): nth term
a(1): first term
n: term position
d: common/constant difference
a(n) = a(1) + (n - 1)d
You should get an equation of a(n) = 6+(18 - 1)17. By following the order of operations, you should receive an 18th term of 295.
