Question

What is the rule of the sequence 25,17,26,23,27,22,16,23

Answer 1

• Given:- 25,17,26,23,27,22,16,23

• To find:- The rule of the sequence

• Solution:- According to the sequence, the format is like,

The first number (-)/(+) the difference between first two numbers = Next number

If here (+) is used then in next format we have to use (-)

and next format is

the gain number (+)/(-) [the difference between first two numbers +1]= next number

And according to the formats

25-8 = 17

then 17+9= 26

then 26-3 = 23

23+ 4= 27

27-5= 22

22-6= 16

16 + 7= 23
