The nth term of an APis 3x+5 find its common difference.

1.	The nth term of an APis 3x+5 find its common difference.
Answer» We are given, an = 3n + 5 which is nth term.So, a1\xa0= 3(1) + 5 = 8and, a2\xa0= 3(2) + 5 =\xa06 + 5 = 11so common difference, d = a2\xa0- a1\xa0= 11 - 8 = 3Therefore common difference is 3
