Hw solution:
given sequence:124, 180, 108, 198, ?, 220
Logic:
1.First find the Consecutive differences (+56, -72, +90 are what you will get)
2. NOW we can write Differences as;
56=7^2+7
-72=-|8^2+8|
90=9^2+9
X=-|10^2+10|
y=11^2+11
;
Verifying :
124+[56 i.e 7^2+7]=180
180-[72 i.e 8^2+8 ]=108
108+[90 i.e 9^2+9]=198
198-[110 i.e 10^2+10]=88 i.e ans of ?
88+[132 i.e 11^2+11] =220
