Answer :
You are adding 12 to each one. So the next two terms would be 52, 64. Have a nice day!
The next term can be determined by adding 12 to the previous term.
So the next two terms in the sequence will be
40+12=52
52+12=64
52 and 64
So the next two terms in the sequence will be
40+12=52
52+12=64
52 and 64
