Question

What is the next term of the geometric sequence 5, 20,80

Answer 1

Answer:

a₄ = 320

Step-by-step explanation:

To obtain a term in a geometric sequence , multiply the previous term by the common ratio r

r = $\frac{a_{2} }{a_{1} }$ = $\frac{20}{5}$ = 4 , then

a₄ = 4 × a₃ = 4 × 80 = 320
