Answer:

1500 + 2250 =

Step-by-step explanation:

Answer:

  • aₙ =  2250n - 750

Step-by-step explanation:

This is an arithmetic progression with:

  • The first term a₁ = 1500
  • Common difference d = 2250

Required expression is:

  • aₙ = a₁ + (n - 1)d
  • aₙ = 1500 + (n - 1)2250 =
  •      1500 + 2250n - 2250 =
  •     2250n - 750
