Here the alternate way is available.... that is
56+16=72
72+18=90
90+20=110
110+22=132
132+24=156
so the 150 is wrong here :)
56+16=72
72+18=90
90+20=110
110+22=132
132+24=156
so the 150 is wrong here :)

Differences b/w the ith term and (i+1)th term starts from 16 and goes on increasing by 2... The last no 150 doesn't satisfy this condition.

72-56=16;
90-72=18;
110-90=20;
132-110=22;
150-132=18; So it is disturbs the sequence of flow.
90-72=18;
110-90=20;
132-110=22;
150-132=18; So it is disturbs the sequence of flow.

56+90=146
(146-2)/2= 72
Similarly
(72+110-2)/2= 90.......
(110+150-2)/2=129 but not 132 so 150 is wrong.
(146-2)/2= 72
Similarly
(72+110-2)/2= 90.......
(110+150-2)/2=129 but not 132 so 150 is wrong.

7^2+7=56
8^2+8=72
9^2+9=90
10^2+10=110
11^2+11=132
12^2+12=156
So 150 is wrong.
8^2+8=72
9^2+9=90
10^2+10=110
11^2+11=132
12^2+12=156
So 150 is wrong.

I think 110 is not divisible by 3. All others are divisible by 3. So 110 is also wrong

Megha you are wrong. 56 is not divisible by 3.

56,72,90,132,150 are divisible by 3
but not 110 so 110 is also answer
but not 110 so 110 is also answer

The difference between the 2 successive numbers ie,72-56=16,90-72=18,110-90=20,132-110=22,{150-132=18}which has to be 24.so 150 is the wrong no.

According to the differences of the respective numbers next term should be 156.
But according to the given explanation the next term should be 172.
Really confusing.
