Yes, to answer your question, the algebraic expression should be w + 3 + n where n = 1  as mentioned by Eugene P. Since they say 'whole number' it will haactions or decimals.  Also they say 'the next ' whole numbers and since whole numbers are counted as 1, 2, 3  etc. next one is always +1 to previous. So +1 to w + 3 is w +3 +1

Hence there is no need for n ; you can directly say W + 3 + 1 or even w + 4

Thanks.

If:  w + 3 is a whole number, then the very

next whole number after it is: (w + 3) + 1 which is w + 4.

w+4 as long as W+3 is a real whole number
