• 0 ## Question Find the next number. Again should be pretty easy.

1, 3, 6, 11, 18, 29, 42, 59, 78, ...

This next one is a mixture of the one above and another number sequence i entered called... Number Sequence by me #4.

1, 1.6, 2.55, 4.14, 6.37, 9.87, ...

The clue kind of basically gives it away.

The last one uses a simple math equation combined of the previous number(p), and then two other well known numbers.

p+x/n

lol. I just noticed that the other two numbers in the equation start with a p.

next # is 101

• 0 good. That one was pretty easy. now try the next one. Only slightly harder and a little more calculator work involved.

Now use now use equation: "previous number" + X prime number/x

find out what the next number needed is

Well, since I solved your number sequence #4, the second sequence was pretty simple for me:

The next number is 14.01 (depending on rounding)

Sequence is: f(n) = f(n-1) + P(n-1)/pi (assume P(0) = 0, and f(0) = 1).

f(1) = 1

f(2) = f(1) + 2/pi = 1.6

f(3) = f(2) + 3/pi = 2.55

f(4) = f(3) + 5/pi = 4.14

f(5) = f(4) + 7/pi = 6.37

f(6) = f(5) + 11/pi = 9.87

f(7) = f(6) + 13/pi = 14.01
