d=_____
n=______​

Answer 1

Answer:

a2-a1=d

d=9

an=a+(n-1)×d

2020=1984+(n-1)×9

2020=1984+9n-9

2020-1984=9n-9

36+9=9n

45=9n

n=5

plese follow and like the answer

Answer 2

d=1993-1984=9

l = a + ( n - 1 ) d

2020 = 1984 + ( n - 1 ) 9

2020-1984/10 = n-1

36/9= n-1

36/9 +1 = n

45/9 = n

n = 5
