Answer:

#2 k + 1#, #(k in NN)#

Explanation:

Denoting some natural number by #k#, the next largest consecutive number may be denoted by #k + 1#.

Their sum will be #k + (k + 1) = 2 k + 1#

(where #k# is an element of the natural numbers, which are conventionally denoted by #NN#, as noted in parentheses in the brief summary answer above)
