It means that a term of a sequence is found by multiplying it by number right after it. Eg: the 7th term is found by multiplying 7 and 8. Can you now work out how to do it?

The nth term of a sequence is n^2+n Two consecutive terms in the sequence have a difference of 32. Work out the two terms.
Thank you!!
let's say the first term if the two consecutive numbers is n. this means that's the next number is n+1. now since the difference is 32,we can say; nth term - (n+1)th term = 32 And we r givene the formula to calculate the nth term of the sequence so; n (n+1) - (n+1)(n+1+1) = 32 n(n+1)-(n+1)(n+2) = 32. Can u do it from here ?

You mean (n+1)th term minus nth term, not other way around

yes thanks for that. however we could also use nth term - (n+1)th term = 32 but u get n as -15 and we know n can never be a negative hence u ignore the negative.
