81
Those are the first six digits of pi. Pi ~= 3.141592653... etc
No, 9 plus pi is not a rational number. While 9 is a rational number, since it can be expressed as a fraction (9/1), pi is an irrational number, meaning it cannot be expressed as a fraction of two integers. The sum of a rational number and an irrational number is always irrational, so 9 plus pi remains irrational.
Yes 9 times pi is an irrational number because it can't be expressed as a fraction
Those are the first 8 decimal places of pi. 3.14159265
9
No, Pi is an irrational number with the first 9 digits being 3.14159265.
9
-18 then -27
9, 81, 6561, 43046721, ...This would be the sequence 9^(2^(n-1))
39. The rule here is starting with the number 9, add (-6 + sequence number * 6). 9 + (-6) = 3 3 + 0 = 3 3 + 6 = 9 9 + 12 = 21 21 + 18 = 39 39 + 24 = 63
The value of pi is an irrational number. Pi is the ratio of the circumference of a circle to the circle's diameter. Also, π is a transcendental number.
The next number in the sequence is 27.
