Answer 1

I think the answer is 3+6=3189

Answer 2

Solution:

→1+2=123        →  The pattern is Unit Digit =1+2=3, ten's digit = 2 × 1=2,Hundred's digit = 1

→2+3=165  , →The pattern is Unit Digit =2+3=5, ten's digit = 2 × 3=6,Hundred's digit = 1

→3+4=1127  →   The pattern is Unit Digit =4+3=7, ten's digit =4 ×3=12 ,

Hundred's digit = 1

→7+8=15615   →The pattern is Unit Digit =8+7=15, ten's digit = 8 × 7=56,  Hundred's digit = 1

→3+6 =1189        → The pattern is Unit Digit =6+3=9, ten's digit = 6×3=18,  Hundred's digit = 1
