Which number is rational? /2 10 O 16

Mathematics
1 answer:
larisa86 [58]3 years ago
6 0

Answer:

16

Step-by-step explanation:

Square root of 2 is irrational. This has been proven by the Pythagoreans (there is a simple proof of that).

pi is also known to be irrational although the proof is a bit more demanding.

Square root of 10 can be written as a product of square root of 5 and square root of 2, which themselves are irrational. Any product involving an irrational number is irrational

Square root of 16 = 4. 4 can be written as a fraction 4/1, or 8/2, 16/4, etc. and therefore is rational by definition.

Let {an} be a sequence that satisfies the recurrence relation an = an-1 + 3 for n = 1, 2, 3, ... , and suppose that a0 = 2. What
Arturiano [62]

Given:

a_n=a_{n-1}+3

a_0=2

To find:

The values a_1,a_2,a_3.

Solution:

We have,

a_n=a_{n-1}+3

For n=1,

a_1=a_{1-1}+3

a_1=a_{0}+3

a_1=2+3

a_1=5

For n=2,

a_2=a_{2-1}+3

a_2=a_{1}+3

a_2=5+3

a_2=8

For n=3,

a_3=a_{3-1}+3

a_3=a_{2}+3

a_3=8+3

a_3=11

Therefore, a_1=5,a_2=8,a_3=11.
