Question

Q.The algebraic form of an arithmetic sequence is 7n+3.
a)what is the remainder when each term of this sequence is divided by 7?​

Answer 1

Answer:

Step-by-step explanation:

a=7n+3

a2=7(n+1)+3

    =7n+7+3

     =7n+10

 a3=7(n+2)+3

      =7n+14+3

       =7n+17

  a4=7(n+3)+3

        =7n+21+3

        =7n+24

now ,

a1/7=3,

a2/7=3

a3/7=3

a4/7=3
