33
Step by Step Explanation:
The first number given is 3.
When we add 2 we get 3+(2)=5
Then in five you have to add (2+2)=4
I.e. 5+4=9
After this you have to add (2+2+2) in 9
9+(2+2+2)=15
Which means you have to add 2 in the previous added number and then add it to the last answer in the sequence.
15+(2+2+2+2)=23
And at the last you get 23+(2+2+2+2+2)=33
