Question

how many 3 digits natural numbers are divisible by 7​

Answer 1

Step-by-step explanation:

3 digit natural numbers are 102,105,108........999

here a=102 and d= 3

tn=999

tn=a+(n-1)d

999=102+(n-1)3

999= 102-3+3n

999=99+3n

999-99=3n

900=3n

n= 300

hence there are 300 natural no. divisible by 3 by this u can solve above
