Question

Write down the first five terms of each of the following sequences, where the nth term are given:

a) 5n​

Answer 1

Answer:

⇒an = 5n

→ a1 = 5(1)

→ a1 = 5

⇒an = 5n

→a2 = 5(2)

→a2 = 10

⇒a3 = 5(3)

→a3 = 15

⇒a4 = 5(4)

→a4 = 20

⇒a5 = 5(5)

→a5 = 25

∴ the first five terms are 5, 10, 15, 20, 25

explanation:

⇒to get the first five terms, substitute the value of n which is the number of terms.
