find three consecutive numbers if three times the middle number is greater than the sum of the first and the last number by 176 About the author Anna
Answer :- Given :- 3 × middle term = first term + last term + 176 To Find :- The three consecutive numbers Solution :- Let the three consecutive numbers be x , x + 1 , x + 2. According to the question :- 3 × middle term = first term + last term + 176 → 3 ( x + 1 ) = x + x + 2 + 176 → 3x + 3 = 2x + 178 → 3x – 2x = 178 – 3 → x = 175 → x + 1 = 175 + 1 = 176 → x + 2 = 175 + 2 = 177 The three consecutive numbers are 175 , 176 , 177. Verification :- → LHS = 3 ( x + 1 ) → LHS = 3 ( 175 + 1 ) → LHS = 3 × 176 → LHS = 528 → RHS = x + x + 2 + 176 → RHS = 175 + 175 + 2 + 176 → RHS = 175 + 177 + 176 → RHS = 528 LHS = RHS Hence verified.

Answer :-
Given :-
To Find :-
Solution :-
Let the three consecutive numbers be x , x + 1 , x + 2.
According to the question :-
3 × middle term = first term + last term + 176
→ 3 ( x + 1 ) = x + x + 2 + 176
→ 3x + 3 = 2x + 178
→ 3x – 2x = 178 – 3
→ x = 175
→ x + 1 = 175 + 1 = 176
→ x + 2 = 175 + 2 = 177
The three consecutive numbers are 175 , 176 , 177.
Verification :-
→ LHS = 3 ( x + 1 )
→ LHS = 3 ( 175 + 1 )
→ LHS = 3 × 176
→ LHS = 528
→ RHS = x + x + 2 + 176
→ RHS = 175 + 175 + 2 + 176
→ RHS = 175 + 177 + 176
→ RHS = 528
LHS = RHS
Hence verified.
