Answer:
12, 36, 108, 324
Step-by-step explanation:
using the recursive formula and a₁ = 4 , then
a₂ = 3a₁ = 3 × 4 = 12
a₃ = 3a₂ = 3 × 12 = 36
a₄ = 3a₃ = 3 × 36 = 108
a₅ = 3a₄ = 3 × 108 = 324
To find the answer, you need to solve for b.
2(2b + 3) = 12 divide both sides by 3
2b + 3 = 6 divide both sides by 2
2b = 3 subtract 3 from both sides
b = 1.5 divide both sides by 2
b = 1.5 satisfies the equation. if you plug 1.5 in, you get that the equation is true.
