Edexcel Higher: November 2017 Paper 1, Q17 1
n is an integer.
Prove algebraically that the sum of n(n + 1) and (n + 1)(n + 2) is
always a square number.
1 2 (n + 1)(n + 2)
= (𝑛2+𝑛+2𝑛+2)
= (𝑛2+3𝑛+2)
= 𝑛 𝑛+1
1 2 n(n + 1)
= 𝑛 𝑛
1 2 𝑛 𝑛 𝑛 𝑛+1
= 𝑛2+2𝑛+1
= (𝑛+1) (𝑛+1)
= 𝑛+1 2
This will always be a square number.
