The sum of the first and last of 4 consecutive odd integers is 36. Largest integer = ?

Question

i’ve been stuck on this for far too long :(

Answer 1

The integers are x, x+2, x+4, and x+6.

x and x+6 are the first and last of four consecutive odd integers. Therefore, (x)+(x+6) = 36. 2x + 6 = 36. 2x = 30.

x + 6 is the largest integer, so (15) + 6 = 21, which is the largest integer.
