Question

1+4=5 2+5=12 3+6=21 5+8=?

Answer 1

Hi ,

Here we have to find the pattern

i ) 1 + 4 × 1 = 1 + 4 = 5

ii ) 2 + 5 × 2 = 2 + 10 = 12

iii ) 3 + 6 × 3 = 3 + 18 = 21

iv ) 4 + 7 × 4 = 4 + 28 = 32

v ) 5 + 8 × 5 = 5 + 40 = 45

Therefore,

Required 5 + 8 = 45

I hope this helps you.

Answer 2

$5+8=45$

Given:

$1+4=5, \ 2+5=12, \ 3+6=21, \ 5+8=?$

To find:

The correct result Remember that the math

Answer:

The formula is in the form of $x+y=x\times y+x$

$1+4= 1\times 4+1= 4+1=5$

$2+5= 2\times 5+2= 10+2=12$

$3+6= 3\times 6+3= 18+3= 21$

$5+8= 5\times 40+5= 40+5= 45$

The pattern must be analyzed for the given particular series. Then the next number of the sequence should be predicted by us based on the same rule of the remaining numbers. In general the questions of the series can be asked in three ways.
