I am studying with igcse edexcel adnd i made that sequence up to test my self and i wanted to know if i needed to know if i needed to know the answer to the sequence. Thanks for your help. Basically, we know that n 2 is part of the nth term for 6, 14, 24, 36, We need to know if the nth term is just n 2 , or if we haven't finished finding parts for the nth term. To do this we compare the sequence of n 2 against 6, 14, 24, 36, Because they're not equal, we're not finished.
So, we'll look at the differences between these sequences to see what is missing from the nth term. This is the 5, 10, 15, 20, The first differences are 3, 5, 7, The second differences are 2, 2, The first differences are 6, 10, 14, The second differences are 4, 4, 4, This means whenever the second difference is 2, it involves an n 2 term; if it's 4, it includes a 2n 2 term; if it's 6, it includes a 3n 2 term, etc.
I was thinking about this problem, and I realized the answer is actually: All possible cominations of ABCD each represents a handshake: This makes sense because Person A shaking person B's hand is the same as person B shaking person A's hand.
We believe this is right! You don't actually need a number, you just need the equation. You can use any letter to make your point Will - N-1 isn;t the total number of handshakes. You need to do the sum first before reaching the handshakes!
Used as a homework but could easily be used in a lesson/5(23).
