HELP PLEASE WITH SIGMA NOTATION PLEAASE

13+8(n-1) is the pattern of how this series goes on where n is the number of entities being added.

Write n at the top of sigma notation which is 5 here. And write the pattern infront of sigma notation which is 13+8(n-1)here.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
