Question

What is the pattern in 21,29,10,37,45,10,53 ?

Answer 1

Answer:

Step-by-step explanation:

Method 1:

If we break down the pattern as set of 3 numbers, it becomes

21,29,10  -- increment by 8 and adding 2 to it to get third number.

37,45,10  - increment by 8 and adding 2 to it to get the third number.

so going by the same analogy the set of three numbers in the third set will be

53, 53+8, 8+2 => 53, 61, 10.

Method 2:

If we assume the third number is constant value say XX = 10 the pattern is

21 , 29, XX, 37, 45, XX, 53 you can see we are incrementing  the next number by 8.

29 - 21 = 8

37 - 29 = 9

45 - 37 = 8

53 - 45 = 8

so the next number after 53 is 53 + 8 = 61 and the next number after this will again be constant XX.

So the series becomes

21,29,10,37,45,10,53 , 61, 10, 69, 77, 10 and so on.
