Answer 2

756 is next number in pattern   12, 36, 84, 180, 372

Step-by-step explanation:

12 = 12 * 1

36 = 12 * 3      ( 3 = 1 *2  + 1)

84 = 12 * 7       ( 7 =3 * 2 + 1)

180 = 12 * 15    ( 15 = 7 * 2 + 1)

372 = 12 * 31     (31 = 15 * 2 + 1)

?  = 12  * 63       ( 63 = 31 * 2 + 1)

12 * 63  = 756

number  = 12 * multiplier

Multiplier  =  2(lastmultiplier) + 1

or

12 * 2   +  12  = 36

36 * 2  + 12  =  84

84 * 2  + 12   = 180

180 * 2  + 12  = 372

372 * 2  + 12  = 756

Tₙ =  2 * Tₙ₋₁   + 12
