Self made doubt

Question

suppose we are given the congestion window 30KB and TO occurs than new th=15 and mss given =2 so when we start with slow start than sequence goes like:-

2 → 4 → 8 → 15 → 17 and so on

or

2 → 4 → 8 → 14 → 16 → 18 and so on?

Comments

2 → 4 → 8 → 15 → 17 and so on
This will be followed as MSS always grow exponentially in slow start phase till threshold value is reached.
