AExplanations:
• Some examples of odd numbers are 1, 3, 5, 7, 9, and 11, we cand see that this is an addition of 2 to the previous number.
So,
• Let x be the smaller inter ... ................(1)
• let x + 2 = the middle interger.......... (2)
therefore the third odd interger will be
• (x+2) +2 = (x+4) ........................................(3)
Solving this according to the given statement will be :
• the sum of 3 times the smaller = 3x
,
• 5 times the largest = 5*(x+4)
combining this would be : 3x + 5(x+4) = 770
Option D is correct .
