Question

he sum of two consecutive odd integers is 28. What are the integers?

Which let statement(s) would you use?

Answer 1

metal...

Answer 2

let n = an integer.
two consecutive odd integers would then take the form
(2n-1), (2n+1)
because we know any integer multiplied by 2 is even
2n mod 2 = 0
and any even integer ±1 is odd
(2n ± 1) mod 2 ≠ 0

so solve, (2n-1)+(2n-1)=28

Answer 3

(2n mod 2 here means that 2 divides 2n evenly. there is no remainder. and there is always a remainder when we divide 2n±1 by 2 (it is 1))
