Prove the following statement using mathematical induction
p(a): 2 3 + 4 + (a - 1) a = 1/2 a(a+1) -1
clearly explain all the steps of your solution

idk

step-by-step explanation:

it has the same slope and a different y-intercept

hope this : )

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110

t= 1/3.

hope this .
