Three different codes to crack: number 1 is just finding the next term in the sequence (not all are arithmetic), number 2 is substituting into nth terms (with a simple quadratic or two) and number 3 is finding and using nth terms of arithmetic sequences. Each has a punchline to a joke to find. I use these for starters and plenaries or homeworks as they are very easy to mark. Typo on number 1 corrected.
Something went wrong, please try again later.
Exactly what I was looking for, thanks!
