And of course the part which tells us that the first term is even too which is 2)

Just the part where you are multiplying the term by 2 should be enough to tell that all terms are even.

Re: The first term of a sequence is 2. All subsequent terms are found by a [#permalink]
1
First term of the sequence is 2, which is even

All subsequent terms are found by adding 3 to the immediately preceding term and then multiplying the sum by 2
Now, we are multiplying the final sum in each case by 2 so all terms will become even by default
So, answer will be all terms are even. But in the interest of understanding let's solve for couple of terms.

Term 2 = (Term 1 + 3)*2 = (2+3)*2 = 5*2 = 10
Term 3 = (Term 2 + 3)*2 = (10+3)*2 = 13*2 = 26
Term 4 = (Term 3 + 3)*2 = (26+3)*2 = 29*2 = 58 and so on...

So, answer will be B
Hope it helps!
