Answer 1

Arithmetic progression

Next 3 terms are 15, 18 and 21.

The sequence is an arithmetic progression (AP)

Looking at the first few terms of the sequence,

there is an addition of 3 from the current term to the next term.

(Value of addition of 3 is a constant)

Hence,

First blank: 12 + 3 = 15

Second blank: 15 + 3 = 18

Third blank: 18 + 3 = 21
