# What number comes next in the pattern: 7, 16, 8, 27, 9?

• 1. Try to notice the differences in each of the following pair of numbers:

7 to 16: +9

16 to 8: -8

8 to 27: +19

27 to 9: -18

1. Do you see a pattern here? From 7 to 16, 9 was added; from 16 to 8, 8 was subtracted; from 8 to 27, 19 was added; from 27 to 9, 18 was subtracted.

2. If this pattern continues, then the sixth number would be 38, which would be 9 + 29. The seventh number would be 10, or 38 - 28.

• I split the sequences into two:

• From: 7, 16, 8, 27, 9

to: 7, 8, 9

and: 16, 27, so the next number is 38.

• Just to show you that there can be more than one LOGICAL answer for a pattern of numbers...

7, 16, 8, 27, 9,

follows this rule:

which would yield this pattern:

7, 16, 8, 27, 9, 40, 10, 55, 11, and so on...

Questions like these are exercises in futility !!

• 1. You have the sequential numbers 7,8,9. In between you have 16,27. The next number should be 11 more.

1. 16 is 9 more than 7. 27 is 19 more than 8. If we keep adding 10, the next number should be 29 more than 9.

Either way the answer is 38.

• There is more than one answer 7 8 9 10 is obvious

8 x2 =16 9x3=27 10x 4=40 11x5=55

• That is not "a" pattern. It is five numbers, which could be followed by ANY number.

7, 16, 8, 27, 9, 1, .... is part of a pattern.

7, 16, 8, 27, 9, 44, ... is ALSO part of a pattern.

Also it could be

7, 16, 8, 27, 9, -3.14, ...

Or any other number you care to write.

• Lots of possibilities. If its 7-8-9 and 2^4-3^3 then 4^2 is 16.

• 10

• 7, 16, 8, 27, 9, ...

38 comes next

• 9+29=38
