13 1000 to
are​

Answer 1

The numbers that lie between 800 and 1000 which are divisible by 13 are

806,819,832....... 988

here a= 806, i = 988 , d= 13

I = a + (n-1) d

988 = 806 + (n-1) 13

=> (n-1) = 182/13

=> (n-1) = 14

=> n=15

so, there are 15 terms between 800band 1000 which divisible by 13
