### Brain Teasers

# Sequence

Series
Series teasers are where you try to complete the sequence of a series of letters, numbers or objects.

Change the position of only one number in the sequence given below in order that the amended sequence corresponds to a palindromic sequence.

1, 4, 9, 6, 2, 1, 5, 10, 4

1, 4, 9, 6, 2, 1, 5, 10, 4

### Hint

Roman Sequence?### Answer

We shift the number 2 to the last position, giving the sequence:1, 4, 9, 6, 1, 5, 10, 4, 2

When each term of the amended sequence is converted to Roman Numerals; without commas it reads as:

IIVIXVIIVXIVII.

(The hint refers to Roman Numerals.)
