Question

The sum of 7 consecutive odd numbers is 91. What is the sum of the two largest numbers in this set?

Answer 1

7 consecutive odd numbers...x, x + 2, x + 4, x + 6, x + 8, x + 10, x + 12

x + x + 2 + x + 4 + x + 6 + x + 8 + x + 10 + x + 12 = 91
7x + 42 = 91
7x = 91 - 42
7x = 49
x = 49/7
x = 7

x + 2 = 7 + 2 = 9
x + 4 = 7 + 4 = 11
x + 6 = 7 + 6 = 13
x + 8 = 7 + 8 = 15
x + 10 = 7 + 10 = 17
x + 12 = 7 + 12 = 19

the sum of the 2 largest numbers is : 17 + 19 = 36 <==
