Sagot :
In all the cases, the number is multiplied by itself and added 1 to it. so the answer is 26
Answer: 26
There is a pattern. It is squared then added with one.
For visual reference-
2=5 (2*2=4, 4+1=5)
3=10 (3*3=9, 9+1=10)
4=17 (4*4=16, 16+1=17)
5=?? (do the same thing)
so
5=26 (5*5=25, 25+1=26)
