Answer:
16, 20, 24
Explanation:
given
4n + 12
This is an nth term formula, which allows us to find any term (
) 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
