The sum of three consecutive odd numbers is 177 what is the smallest of the three numbers

Assume that the three numbers are :
x , x+2 and x+4

Their sum is 177
→ x + (x+2) + (x+4) = 177

simplify it
→ 3x + 6 = 177

minus 6
→ 3x = 171

divide by 3
→ x = 57

so the three numbers are : 57 59 61

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
