Please urgent Complete the proof for Theorem 3-13.

1. l||m Given
2. m∠1 = m∠3 Substitution
3. m∠2 = m∠3 Vertical angles are equal.
4. m∠1 = m∠2 If lines are ||, corresponding angles are equal.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
