here a= 105l= 994n=?d= 7so994 = 105+(n-1) 7= 105+7n-7994= 98+7n994-98 = 7n896/7 = nn= 128so 128 three digit numbers are divisible by 7
Given,A(first term)=105,An(last term)=994,d( common difference)=7,n=?An=A+(n-1)d995=105+(n-1)7887=(n-1)7n-1=127n=127+1=128Hence, there are total 128 three digit no. divisible by 7.
