Numbers begin from 105 .......994
here a= 105
l= 994
n=?
d= 7
so
994 = 105+(n-1) 7
= 105+7n-7
994= 98+7n
994-98 = 7n
896/7 = n
n= 128
so 128 three digit numbers are divisible by 7
I guess......

ANSWER:-✔✔⤵️⤵️
Here this is an AP
105,112,119.........994
In this AP, a=105, d=7, nth term(an)=994
So, an=a+(n-1)d
994=105+(n-1)7
994-105=7n-7
889+7=7n
896=7n
n=896/7=128
So there are 128 three digit numbers
which are divisible by 7
