Please help me!!!! Find the 56th term of an arithmetic sequence if the common difference is

Answer:
7 + 55[tex]\sqrt{11}[/tex]
Step-by-step explanation:
term one is 7
so term 2 is 7 + [tex]\sqrt{11}[/tex]
and term 3 is 7 + 2[tex]\sqrt{11}[/tex]
common pattern here: 7 + (n-1)[tex]\sqrt{11}[/tex]
when n = 56
7 + 55[tex]\sqrt{11}[/tex]
