2. Find three consecutive odd integers such that the sum of the second and the third is equal to four times the first.
Answer provided by our tutors
the three consecutive odd integers can be written as:
2x - 1, 2x + 1, 2x + 3, where x is integer
the sum of the second and the third is equal to four times the first
2x + 1 + 2x + 3 = 4(2x - 1)
by solving we find
x = 2

2*2 - 1 = 3
2*2 + 1 = 5
2*2 + 3 = 7
the three consecutive odd integers are 3, 5 and 7.
