TEA [102]3 years ago
5 0

Answer:

Rational

Step-by-step explanation:

2^{-3} simplifies to \frac{1}{8}.

Therefore, it is rational.

2^{-3}\\\\\text {Apply negative exponent rule: } a^{-n} = \frac{1}{a^n} \\2^{-3}= \frac{1}{2^3}\\ \rightarrow 2^3 = 2*2*2=8\\\boxed{2^{-3}=\frac{1}{8}}

Write the first three terms of the sequence defined by the recursive formula if a1=2.
gogolik [260]

The first three terms of the sequence defined by the recursive formula are 2, -7/2 and -3/2

Given:

an =  \frac{an - 1}{4}  - 2

where,

n = number of terms

First term, a1 = 2

Second term, a2

an =  \frac{an - 1}{4}  - 2

a2 = {(2 - 1)/ 4} - 2

= 1/4 - 2

= (1-8) / 4

= - 7/4

Third term, a3

= {(3-1) / 4} - 2

= 2/4 - 2

= 1/2 - 2

= (1-4) / 2

= -3/2

Therefore, the first three terms of the sequence defined by the recursive formula are 2, -7/2 and -3/2
