Study the number pattern. What is the number in the 72nd position?
Sets of 3
(Set 1) 1st, 2nd, 3rd: 2, 3, 4
(Set 2) 4th, 5th, 6th: 3, 4, 5
(Set 3) 7th, 8th, 9th: 4, 5, 6
(Set 4) 10th, 11th, 12th: 5, 6, 7
Formula:
Total number of sets = Position number ÷ 3
Value of the 1st number in each set of 3 = Set number + 1
Number of sets at position 72th
= 72 ÷ 3
= 24 r 0
At Set 24,
First number = 24 + 1 = 25
(Set 24): 25, 26, 27
The 72nd position is in set 24.
Since the remainder is 0, the number in the 72nd position is 27.
Answer(s): 27
