Question

Show that the following sequence is arithmetic. Find the first term and the common difference for a(n)=(3n+4)

Answer 1

Step-by-step explanation:

a(n)= 3n+4

so, a(1)=3.1+4=7

a(2)=3.2+4=10

a(3)=3. 3+4=13

so ap= a(1),a(2),a(3),.......

ap=7,10,13,......

first term=7 andcomman diff.= 3
