2+1=23
3+1=34
4+2=26
6+3=29
Then
7+1=??

Answer 1

38 is the correct answer

Answer 2

•Given :-

2+1=23

3+1=34

4+2=26

6+3=29

•To find:-

7+1=??

•Solution:-

One format is like

(prime number + another number)

= [that perticular prime number×10 +(prime number + another number) ]

so

2+1= 2×10 +3 = 23

3+1= 3×10+4 = 34

and

another format is like

(composite number + another number)

= [(the first composite number 2)×10 +(composite number + another number) ]

so

4+2=2×10= 26

6+3= 2×10= 29

and now

7+1 is following the format —›(prime number + another number)

so the answer is = [that perticular prime number×10 +(prime number + another number) ] = 7×10 +7+1 = 78
