Answer :

100

Step-by-step explanation:

A.P = 50 , 40 , 30 , .......

a = 50

d = ( - 10 )

tn = ( - 940 )

tn = a + ( n - 1 ) d

- 940 = 50 + ( n - 1 ) ( - 10 )

- 940 = 50 + ( - 10 n + 10 )

- 940 = 50 - 10n + 10

- 940 = 60 - 10n

- 940 - 60 = ( - 10n )

- 1000 = ( - 10n )

n = - 1000

- 10

n = 100
