Answer:
The 54th term is -855
Step-by-step explanation:
Since the sequence is arithmetic, then we have to use the rule of the nth term
a is the first term
d is the common difference
n is the position
The given sequence is -7, -23, -39
a=-7
d=-23-(-7)=-23+6=-16
We need to find the 54th term
n=54
Substitute them in the rule
Solve it:
The 54th term is -855
