A sequence has an nth term of n2 - 6n + 7 Work out which term in the sequence has a value of 23. Here are the first 5 terms of a quadratic sequence 11 20 31 44 Find an expression, in terms of n, for the nth term of this quadratic sequence.
A quadratic sequence is a sequence whose n^ {th} term formula is a quadratic i.e. it has an n^2 term, so takes the form, \textcolor {red} {a}n^2+\textcolor {blue} {b}n+\textcolor {limegreen} {c}, where a, b, and c are all numbers.
• Read each question carefully before you start to answer it. • Keep an eye on the time. • Try to answer every question. • Check your answers if you have time at the end
Quadratic sequence formula. The quadratic sequence formula is: an^{2}+bn+c . Where, a, b and c are constants (numbers on their own) n is the term position. We can use the quadratic sequence formula by looking at the general case below: Let’s use this to work out the n^{th} term of the quadratic sequence, 4, 5, 8, 13, 20, ...
