Next number is 252.
nth term is n³ + n²
or another method 2 = 1. 2
12 = 2 . 6 = 4 .3
36 = 3. 12 = 9 .4
80 = 5 . 4^2 = 16 .5
150 = = 25 .6
A(n) = = n^2 .(n + 1)
next
A(6) = 6^2 .7 =36 .7 = 252
plz mark as best

the terms are in the order x² + x³
i.e. 1² + 1³ = 2
again 2² + 2³ = 12
so for 6 th term
6² + 6³ = 252
i.e. 1² + 1³ = 2
again 2² + 2³ = 12
so for 6 th term
6² + 6³ = 252
X2+x3...... ans. 252
