Find the pairs of consecutive even positive integers both of which are smaller than 10 and their sum of more than 11
(6, 8) and (4, 8)
(4, 8)
(6, 8)
(6, 4)(4, 2)
Even integers smaller than 10 are 2, 4, 6, 8 now the sum must be more than 11 so the pair of number is (6, 8)
Find all pairs if consecutive odd positive integers,both of which are smaller than 10,such that their sum is more than 11.
Find all pairs of consecutive even positive integers,both of which are larger than 5,such that their sum is less than 23.
