in 4 line we get 3 term also as 6 so add 6 to 26 ,we get 4 term in 3 line as 32
now add 32 to last term in 2 line 71+32=103
now add this 103 to 156=156+103=259

2*2=4
3*5=15
4*10=40
5*17=85
6*26=156
7*37=259
difference between 5-2=3, in next line difference between 10-5=5, third line 17-10=7 and so on..therefore for the next number, the difference should be 11. 37-26=11. answer will be 7*37=259
