Question

$4+1=5,5+2=12,3+6=21,8+11=?$. Complete it.

Answer 1

In the given pattern $4+1=5,5+2=12,3+6=21,8+11=?$, we have to study the pattern

Here the addition process is followed in a series of logical sequences as

$1+4=5$

$5+2=7\&7+5=12$

$6+3=9\&12+9=21$

$8+11=19\&21+19=40$

Hence, the required answer is $40$.
