Question

Find the simplest form of the general term for the sequence 11, 15, 19, 23, .

Answer 1

The general term of an arithmetic sequence is
  an = a1 +(n-1)d
Your sequence has first term a1 = 11 and common difference d = 4. Then the general term is
  an = 11 + (n-1)*4

The simplest form of the general term is
  an = 7 + 4n
