12, 36, 80, 150,.... ?
Read Solution (Total 10)
-
- 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 - 12 years agoHelpfull: Yes(63) No(0)
- 2^2*3=12
3^2*4=36
4^2*5=80
5^2*6=150
6^2*7=252 - 12 years agoHelpfull: Yes(24) No(1)
- (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 - 12 years agoHelpfull: Yes(8) No(1)
- 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. :) - 12 years agoHelpfull: Yes(5) No(1)
- ans is 252
4*3=12
6*6=36
8*10=80
10*15=150
12*21=252 - 10 years agoHelpfull: Yes(3) No(1)
- 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 - 12 years agoHelpfull: Yes(2) No(1)
- 2^3+2^2 =12
3^3+3^3 =36
4^3+4^2 =80
5^3+5^2 =150
6^3+6^2 =252
