# Unusual Math logic brain teaser

Best answer

*96*

1*(4+1)=5

2*(5+1)=12

3*(6+1)=21

8*(11+1)=96

**92**

(1*4)+1=5

(2*5)+2=12

(3*6)+3=21

(8*11)+4=92

1+4=5

5+2+5=12

12+3+6=21

21+8+11=40

Each equation is independent of previous result, Only Position of equation in the series matters. hence, answer will be 96 as given by dyj

1+(4*1)=5

2+(5*2)=12

3+(6*3)=21

8+(11+8)=96

I solved this a longer way with addition.

Answer = NUM1+NUM2+PREVIOUS SUM

OR sn = x+y+ s(n-1)

1+4 + 0 = 5

2+5+ 5=12

3+6+12=21

4+7+21=32

5+8+32=45

…

8+11+77=96

Above answers are obviously better, but I chimed in anyways

Found a bit of a unique solution to this one it seems

1 + 4 = 5 (base 6)

2 + 5 = 12 (base 5)

3 + 6 = 21 (base 4)

8 + 11 = **201** (base 3)
