Study the number pattern. What is the number in the 83rd 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 83th
= 83 ÷ 3
= 27 r 2
At Set 27,
First number = 27 + 1 = 28
(Set 27): 28, 29, 30
(Set 28): 29, 30, 31
The 83rd position is in set 28.
Since the remainder is 2, the number in the 83rd position is 30.
Answer(s): 30
