Answer:
A. 8, 16, 32, 64....
Step-by-step explanation:
to solve, we can plug in the numbers 1, 2, 3, and 4 for the letter n in the equation. we got these numbers since the problem is asking us for the first 4 numbers in the sequence
[tex]a_n = 4 × 2^n[/tex]
[tex]a_1 = 4 × 2^1[/tex] = 4 × 2 = 8
[tex]a_2 = 4 × 2^2[/tex] = 4 × 4 = 16
[tex]a_3 = 4 × 2^3[/tex] = 4 × 8 = 32
[tex]a_4 = 4 × 2^4[/tex] = 4 × 16 = 64
so the first four terms in the sequence are 8, 16, 32, and 64, which is choice A
