Question

how many three digit even numbers are divisible by 13

Answer 1

Answer:

Step-by-step explanation:

Here ,

a= 104 and tn= 988

Even number occurs after 26

Therefore d = 26 .....(if d is 26 each no.will be divisible by 13)

Now,

tn= a + (n-1)d

988= 104+(n-1)26

988= 104+ 26n-26

988=78+ 26n

988-78= 26n

910= 26n

910/26=n

n = 35

Therefore ,there are 35 even three digit numbers divisible by 13

Answer 2

Answer:

35 numbers are divisible
