Question

Find the first 4 terms of the sequence defined by t

n = n(n + 2).​

Answer 1

Answer:

3,8,15,24

Step-by-step explanation:

find the first 4 terms of sequence, given

tₙ = n(n+2) , where tₙ is the n'th term

t₁ = 1(1+2) = 1(3) = 3

t₂ = 2(2+2) = 2(4) = 8

t₃  = 3(3+2) = 3(5) = 15

t₄ = 4(4+2) = 4(6) = 24
