Question

complete the following. 128,64,32,_,_,_

Answer 1

Answer:

128, 64, 32, 16, 8, 4

Step-by-step explanation:

Number Series :  128, 64, 32, _, _ ,_

This is a GP:

First Term = a = 128

Common Ratio = r = a2 ÷ a1 = 64 ÷ 128 = 0.5

Find the nth term:

Tn = a x rⁿ⁻¹

Tn = 128 x 0.5ⁿ⁻¹

Find the next 3 terms:

T4 = 128 x 0.5³ = 16

T5 = 128 x 0.5⁴ = 8

T6 = 128 x 0.5⁵ = 4

Answer: The next three numbers are 16, 8 and 4
