Lennon Zamora · Answer 1

You should the number they give you 1419 and divide that by two since there is only to people and you get your answer 709.5

Lindsay Beasley · Answer 2

If sum of numbers (a) + (b) is 1419 and

(a) and (b) are neighbors, whe have:

a + b = 1419 and b-a = 1;

a + b = 1419 and a = b-1;

so we have b-1 + b = 1419 2b = 1420 b=710 and a = 709

Answer: 710 and 709
