Finding the nth term of this sequence: (by the way I'm learning quadratic sequences= -2 -8 -18 -32 -50

n^2+2n+1

Step-by-step explanation:

-2-8-18-32-50

difference=-6-10-14-18

common differences=-4-4-4-4-4

 -2-8-18-32-50

n^2=1,4,9,16,25

minus it

=-1,-4,-9,-16,-25

differences 2,5,7,9

common differences=2

2,4,6,8

so 2n+1

so the answer is n^2+2n+1

answer: it's a
