Answer:

The nth term of a sequence is 2n + 1

The nth term of a different sequence is 3n  1

Work out the three numbers that are

in both sequences

and

between 20 and 40

Now the three numbers I managed to get are 25, 31 and 37 (as I assumed it meant the output of both of these sequences needs to be the same as well as being in between 20 and 40). For example 2x18+1= 37 as does 3x12+1= 37
