900 3 digit numbers 100 through 999
about 6/7 are not multiples of 7
900x6/7 = 5400/7 = 771 3/7
105 is 1st divisible by 7
994 is the last 3 digit divisible by 7
994-105= 889
add 1 = 890
890/7 = 127 1/7
900-127 = 772 or 773 not divisible by 7
105,112,119
126, 133, 140
147, 154, 161
168, 175, 182
189, 196, 14 in the hundreds
14x9= 126, 899-126= 773
994, 987, 980
973, 966, 959,
952, 945, 938
931, 924, 917
910, 903 14 in the 900's
either 772 and 773 or 774
my guess is 773
each of the hundreds (100's, 200's, 300's, ... 800's, 900's) has 14 divisible by 7, 86 not divisible by 7
86x9 =774
