Study the number pattern. What is the number in the 78th 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 78th
= 78 ÷ 3
= 26 r 0
At Set 26,
First number = 26 + 1 = 27
(Set 26): 27, 28, 29
The 78th position is in set 26.
Since the remainder is 0, the number in the 78th position is 29.
Answer(s): 29
