first find the difference
4,10,18,36,60,_,_
10-4=6.......(1)
18-10=8.....(2)
36-18=18....(3)
60-36=24.....(4)
now find
2^2+2=6
3^2-1=8
4^2+2=18
5^2-1=24
6^2+2=38
7^2-1=48
so for next two term the difference will be 38 and 48 respectively
so add 38 to 60,98 will come,then again add 48 to it,146 will come
so the series will look like this
4,10,18,36,60,98,146(ans)

first divide the whole series with 2 as of which the req. equ comes out like as follows-
2,5,9,18,30
Now the difference b/w all of these will become somewhat like 3,4,9,12.
multiply each no. with 3 so as per the pattern boles, the ans will come out to be 27.

4,10,18,36,6090,_,_
10-4=6.......(1)
18-10=8.....(2)
36-18=18.....(3)
60-36=24.....(4)
1st eqn multiply wit 3 we get (18) 3 eqn
similar 2nd eqn *3 = 24
3rd eqn *3 =54
4th eqn *3 =72
then 60+54=114
114+72=186
hence ans=114,186

10-4=6.......(1)
18-10=8.....(2)
36-18.....(3)
60-36=24.....(4)
1 eqn(6) multiply wit 3 we get (18) 3 eqn
similar 2nd eqn *3 = 24
3rd eqn *3 =54
4th eqn *3 =72
so ans 54, 72
