Question

Answer 1

hope this helps u

Answer:

common difference = -5

Step-by-step explanation:

an= 4-5n

if n = 1

a1 = 4-5*1= -1

if n = 2

a2 = 4-5*2= 4-10= -6

common difference = a2 - a1

                                 = -6 - (-1)

                                 = -6+1

                                  = -5
