What is the 8th number in the geometric sequence 8, 16, 32, 64, 128...?

2¹¹

Step-by-step explanation:

8th term is given by,

ar⁷

Here a is first term and r is common ratio.

ar⁷ = 16 × 2⁷ = 2⁴ × 2⁷ = 2¹¹

So 2¹¹ is the answer.

Step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

answer is because 4×10=40

and 98×4= is 392

40,392
