Answer:
The 21st term is 137.
Step-by-step explanation:
Arithmetic progression:
In an arithmetic progression the difference between consecutive terms is always the same, and its called common difference.
The nth term is given by:
In which is the first term and d is the common difference.
The first two terms are -3, 4.
This means that
So
The 21st term is
The 21st term is 137.
