ANSWER:

Aₙ = n( n + 2)

= n² + 2n

first TERM = a₁ = (1)² + 2(1) = 1 + 2 = 3

2nd term = a₂ = (2)² + 2(2) = 4 + 4 = 8

3rd term = a₃ = (3)² + 2(3) = 9 + 6 = 15

4th term = a₄ = (4)² + 2(4) = 16 + 8 = 24

5th term = a₅ = (5)² + 2(5) = 25 + 10 = 35

Step-by-step explanation:

im not sure if this is the answer you need but i hope it helps you
