The series goes like this........
15, 12+52=26, 22+62=40, 42+02=16, 12+62=37, 32+72=58,
52+82=89,...........I guess now u know the next term which is....82+92=145
So its the series of sum of squares of the digits of previous term.
16 to 26 (+10) 26 to 21 (-5) 21 to 31 (+10) 31 (-5) = 26 26
26
The pattern here seems to be to add ten, then subtract five.16 + 10 = 2626 - 5 = 2121 + 10 = 31So: 31 - 5 = 26
a
The next number is 41 because the numbers are increasing by increments of 5
26
16 to 26 (+10) 26 to 21 (-5) 21 to 31 (+10) 31 (-5) = 26 26
16+10= 26 26-5= 21 21+10= 31 31-5= 26 The answer is 26
16+10=26 26-5=21 21+10=31 31-5=26 so the next no. is 26...
16+10=26 26-5=21 21+10=31 31-5=26 26+10=36
33
First put them in order:11, 12, 13, 15, 16, 26, 26.Then use your fingers the numbers at the opposite ends:11, 12, 13, 15, 16, 26, 26.Then keep moving in11, 12, 13, 15, 16, 26, 26.11, 12, 13, 15, 16, 26, 26.Until you come to the middle:11, 12, 13, 15, 16, 26, 26.So the median is 15.
26
(13 + 15 + 26 + 11 + 26 + 16 + 12)/7 = 17 ====
The pattern here seems to be to add ten, then subtract five.16 + 10 = 2626 - 5 = 2121 + 10 = 31So: 31 - 5 = 26
26
i this next word will be 26. because 16+10=26 26-5=21 21+10=31 31-5=26
