16, 20, and 24

==========

Substitute values of n into the expression.

  • For n = 1, the expression ⇒ 4(1) + 12 = 4 + 12 = 16.
  • For n = 2, the expression ⇒ 4(2) + 12 = 8 + 12 = 20.
  • For n = 3, the expression ⇒ 4(3) + 12 = 12 + 12 = 24.

Answer:

16, 20, 24

Explanation:

given

4n + 12

This is an nth term formula, which allows us to find any term (
a_(n) ) in the sequence, where n is the term number , by substituting the value of n into it, then

to find the first 3 terms, substitute n = 1, 2, 3 into it

a₁ = 4(1) + 12 = 4 + 12 = 16

a₂ = 4(2) + 12 = 8 + 12 = 20

a₃ = 4(3) + 12 = 12 + 12 = 24

The first 3 terms of this sequence are 16 , 20 , 24
