Read the row of digits below from left to right.
7 3 7 3 0 6 6 4 3 1 1 3 1 8 0 1 3 1 3 0 5 3 9 1 4 9
How many 3s in this row have the same digit directly before them and directly after them?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 3
Check every 3 in the row: the digit just before it and the digit just after it must be the same.
Place 2: 7 3 7 — counts
Place 4: 7 3 0 — does not count (7 and 0 are different)
Place 9: 4 3 1 — does not count (4 and 1 are different)
Place 12: 1 3 1 — counts
Place 17: 1 3 1 — counts
Place 19: 1 3 0 — does not count (1 and 0 are different)
Place 22: 5 3 9 — does not count (5 and 9 are different)
So the answer is 3.
