1+2+3+(4)=10
2+3+4+(4)=13
4+5+6+(4)=19
5+6+7+(4)=22
similarly.
6+7+8+(4)=25
hence 25 is the ans..

since in 1+2+3=10 (1+2+3+4(add extra four) )
similarly 2+3+4=13 (2+3+4+4(add extra four) )
4+5+6=19 (4+5+6+4(add extra four) )
5+6+7=22 (5+6+7+4( add extra four) )

``````hence 6+7+8=25(6+7+8+4(add extra four) )
``````

since
(1+2+ 3)+ 4=10
(2 +3+ 4)+ 4=13
(4 +5+ 6)+ 4=19
(5 +6+ 7)+ 4=22
then
(6 +7+ 8)+ 4=25
