Answer:
5 5 5 5=Y
Explanation:
Looking at the number pattern
1 1 1 1= R
2 2 2 2= T
3 3 3 3= E
4 4 4 4= N
To crack this, follow these steps
- Introduce an addition sign in between the numbers
- Write the sum in words
- Pick the last letter of the word
This is shown below:
1+1+1+1 = FOUR (R)
2+2+2+2 = EIGHT (T)
3+3+3+3 = TWELVE (E)
4+4+4+4 = SIXTEEN (N)
5+5+5+5 = TWENTY (Y)
Therefore, 5 5 5 5 = Y
