f[0] means “Is it an AP with first 0 elements?” - Yes it is. So, f[0] = true
f[1] means “Is it an AP with first 1 elements?” - Yes, a single element is in AP so, f[1] = true;
similarly, f[2] is true since any two numbers will always be in AP.
And same is true if we took elements from backwards. Hope it helps.
