# Write the first five terms of each of the sequences in Exercises 1 to 6 whose nth terms are: a_{n} = n (n + 2)

**Solution:**

a_{n} = n (n + 2)

Substituting n = 1, 2, 3, 4, 5

a_{1} = 1(1 + 2) = 3

a_{2} = 2(2 + 2) = 8

a_{3} = 3(3 + 2) = 15

a_{4} = 4(4 + 2) = 24

a_{5} = 5(5 + 2) = 35

Therefore, the required terms are 3, 8, 15, 24 and 35
