Answer 1

Answer 2

Answer:

no

Step-by-step explanation:

Given  a=8

           d=13-8=5

Consider that 402 is a term of this sequence

as we know  tₙ=a+(n-1)d

                     402=8+(n-1)5

                  402=8+5n-5

                     402=5n+3

                        5n=399

                           n=399/5

it should not be a fraction

Hence 402 is not a term of this sequence
