The simplest logic I think is 2014 × 2015 +(2014×2013)

I use simple logic as if the term is x+y then i did x*(x+y-1)

such that:

2*(2+3-1)=8

3*(3+7-1)=27

4*(4+5-1)=32

. . .

2014*(2014+2015-1)=8112392

Take the numbers on the left as a and b,then do: a*(a+b)-b

For Example:

2*(2+3)-2=8

3*(3+7)-3=27

Therefore: 2014*(2014+2015)-2014=8112392

Reply if you have any doubts.

Just a simple logic.....Every even of two no. In given addition perfectly divided by the of given addition . ....2014 must be divisible in any of the options. .....which is 1st option
