Question

the sum of four consecutive odd numbers is 80. What is the largest of these numbers?

Answer 1

(2x +1) + (2x +3) + (2x +5) + (2x +7) = 80
8x + 16 = 80
8x = 64
x =8
Largest number is 23

Answer 2

Thanks

Answer 3

By the way, the reason I set up the problem with 2x+1 instead of the usual x+1 is that 2x+1 always produces an odd number.
