Q. What is the next number of the following sequence
12, 36, 80, 150,.... ?

• ans is 252
  12=2^3+2^2
  36=3^3+3^2
  80=4^3+4^2
  150=5^3+5^2
  =>6^3+6^2=216+36=252

• 2^2*3=12
  3^2*4=36
  4^2*5=80
  5^2*6=150
  6^2*7=252

• (cube of 2 + square of 2) (cube of 3 + square of 3) (cube of 4 + square of 4)
  (cube of 5 + square of 5),
  so
  (cube of 6 + square of 6)=252

• 36-12=24, 80-36=44, 150-80=70,
  and 44-24=20, 70-44=26, next difference should be 26+6=32
  now, 70+32=102 and the next number will be 150+102=252. :)

• The given pattern is like this :
  12=2^3+2^2
  36=3^3+3^2
  80=4^3+4^2
  150=5^3+5^2
  so, the next term will be 6^3+6^2=252
  
  =>6^3+6^2=216+36=252

• 2*6 =12 (12-6)=6
  3*12 =36 (20-12)=8
  4*20 =80 (30-20)=10
  5*30 =150 (x-30)=12
  6*42 =252 x=42
