# What number in the series is wrong and should be replaced 2 4 8 16 20 22 44 46?

#### already exists.

#### already exists as an alternate of this question.

Would you like to make it the primary and merge this question into it?

#### exists and is an alternate of .

Any one of them could be wrong. Short of reading the mind of the person who posed the question, there is no way of determining which of the infinitely many solutions is the "correct" one.

For example,
2 is wrong. The rule for the sequence is:
t(n) = (-23*n^6 + 636*n^5 - 7010*n^4 + 39330*n^3 - 118247*n^2 + 181434*n - 110520)/180 and the correct value is 80; or
4 is wrong. The rule for the sequence is different and the correct value is 15.71; or
8 is wrong. The rule for the sequence is different and the correct value is 4.1; or
16 is wrong. The rule for the sequence is different and the correct value is 18.34; or
20 is wrong. The rule for the sequence is different and the correct value is 17.63; or
22 is wrong. The rule for the sequence is different and the correct value is 25.87; or
44 is wrong. The rule for the sequence is different and the correct value is 32.14; or
46 is wrong. The rule for the sequence is different and the correct value is 127.61.
Take your pick! And these are only polynomial solutions.

A different approach:
8 is the only number whose English name starts with a vowel - change it to 7 or 9.
---
Sequential approach:
Replace 16 with 10 to follow the alternating sequence of addition then multiplication by 2.
2+2=4 x2=8 +2=10 x2=20 +2=22 x2=44 +2=46
This was the solution presented by the original asker circa 2005.

# Which one of the numbers in the series is wrong and should be replaced 2 - 4 - 8 - 16 - 20 - 22 - 44 - 46?

16 should be replaced by 10   1x2=2, 2+2=4, 4x2=8, 8+2=10, 10x2=20, 20+2=22, 22x2=44, 44+2=46   it would continue:   92, 94, 188, 190, 380, 382...

# Which number should come next in the series 4 5 8 17 44?

  5 - 4 = 1 = 3^0 8 - 5 = 3 = 3^1 17 - 8 = 9 = 3^2 44-17 = 27 = 3^3 X - 44 = 3^4 = 81 X = 125

# Witch should be replace in the sequence 2 4 8 16 20 22?

  Well, I just try it: 2 plus 2 is 4 4 plus 4 is 8 8 plus 8 is 16 >> +2 , +4, +8 Now it's getting less again 16 plus 4 is 20 20 plus 2 is 22 And the next w

# What is the Wrong number in this sequence 2-4-8-16-20-22-44-46?

16 should be 10 because the pattern is adding by 2 then multiplying by 2 so... 2... 2+2=4... 4*2=8... 8+2=10... get it and so on

# What number comes next 1-2-4-8-10-20-22?

44 because you add two and then you multiply by two 1*2=2 2+2=4 4*2=8 8+2=10 10*2=20 20+2=22 22*2=44...etc

# Has these numbers ever come out on the lottery 8 13 20 22 35 44?

Well mate if they have I think it's best you didn't know about it. Other wise you would be beating yourself up for the rest of your life wishing you put the numbers in sooner.

# Are there any wrong numbers in this series 2 - 4 - 8 - 16 - 20 - 22 - 44 - 46?

That depends on the definition of the list. If the list was supposed to show a set of positive even integers in ascending order, then it's entirely correct. If it was supposed

This is wrong. It should be    16 should be replaced by 10   2+2=4, 4x2=8, 8+2=10, 10x2=20, 20+2=22, 22x2=44, 44+2=46

# What number has the multiples of 1 2 4 5 8 10 16 20 40 80?

No number has the multiples of 1, 2, 4, 5, 8, 10, 16, 20, 40, 80, but the number 80 (and all its multiples: 160, 240, 320, 400, ...) has them all as FACTORS.
