Answer 1

Answer:13

Explanation:

Answer 2

5+8 =45

Explanation:

Given the pattern

• 1+4=5
• 2+5=12
• 3+6=21

Let us represent it with the form: a+b=c

The key is: a+(b X a) =c

Let us verify

• In 1+4 =5, a=1,b=4, a+(b X a)=1+(4X1)=1+4=5=c

• In 2+5=12, a=2, b=5, a+(b X a)=2+(5X2)=2+10=12=c
• In 3+6=21, a=3, b=6, a+(b X a)=3+(6X3)=3+18=21=c

Therefore:

In 5+8, a=5. b=8

a+(b X a) = 5 +(8 X 5) =5+40 =45

5+8 =45
