4,10,18,36,60,__,__

• 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

  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
