Answer:
98is correct answer please mark me branliest
Answer:
There are 3 possible answers given here i.e., 98, 99 ,119.
While 99 and 119 are equally justifiable, if the next step would be 200+199, you might add 11 or 48 respectively to compute the answer.
You might argue why 200 and 199. Since you should progress 1 number at a time. For those, my answer follows:
The series is simple.
Odd+ Even = Something.
3+2=7
5+4=23
7+6=47
9+8=79
Then you switch to
Even+Odd which by similar justification should not give similar results. By your standards it shoud be 11+10.
Logic is something that should be applicable to entire range of numbers with no exceptions even if the puzzle does not call for. Thus ruling out the justification for 99 and 119.
By that principle of logic,
a*b+(b-1) is the only one that satisfies the condition and gives reliable results throughout the number range.
Hence, 98.
