Easy way to do quadratic sequences

WebThe easiest way is probably to look at the sequence for a while, and realize: a_1_=1 a_2_=1+2 a_3_=1+2+3 a_4_=1+2+3+4 --- a_n_=1+2+3+4+---+n So we will need to add the numbers all the way from 1 to n Intrestingly, such a formula have already been derived. I will not explain it here, but the formula is: a_n_=n (1 + n) /2 WebThere are many ways to solve quadratics. All quadratic equations can be written in the form \ (ax^2 + bx + c = 0\) where \ (a\), \ (b\) and \ (c\) are numbers (\ (a\) cannot be equal to 0, but...

WebIf you have a general quadratic equation like this: ax^2+bx+c=0 ax2 + bx + c = 0 Then the formula will help you find the roots of a quadratic equation, i.e. the values of x x where this equation is solved. The quadratic formula x=\dfrac {-b\pm\sqrt {b^2-4ac}} {2a} x = 2a−b ± b2 − 4ac It may look a little scary, but you’ll get used to it quickly!

WebThe best way to find the general term of a quadratic sequence is to start with a table of first and second differences.
