Question

The n th term of an arithmetic series is 3-5n then find its common difference​

Answer 1

Step-by-step explanation:

nth term=a

n

=3n+5(given)

a

(n−1)

=3(n−1)+5=3n+2

Common difference =d=a

n

−a

(n−1)

=(3n+5)−(3n+2)

=3n+5−3n−2

=3

Therefore, common difference is 3.

Vo) LTE LTE1 44.

=3n+5(given)

a

(n-1)

=3(n-1)+5=3n+2

Common difference =d=a

n

-a

(n-1)

=(3n+5)-(3n+2)

=3n+5-3n-2

=3

Therefore, common difference is 3.
