Let three consecutive multiple of 7 be 7z , 7z+7 +7z+14

7z+7z+7+7z+14 = 777

21z+21 = 777

21z= 777-21

21z = 756

z=756/21=36

so the three consecutive no. are

7*36 =252

7*36+7 = 252+7 =259

7*36+14 = 252+14 =266

x+x+7+x+14 = 777
3x+7+14=777
3x+21=777
3x=777-21
3x=756
x=756/3
=252
1st no. = 252
2nd no. = 252+7 =259
3rd no. = 252 +14=266
