I think its 210 because there are 7 letters and 3 vowels so the permutation would be 7 P 3.
He earns 23 000 000 per 80 games for 48min
Per game he earns

If he earns 782 500 per game he earns 5 989,5833 per minute

If he played 2/3 of the time he played 32min which means he earned...

So he trained 35hours for a 48min match
Together that is 35.8hours
But I dont think this really matters here you just have to multiply 24453.125 with 60
And you get his hourly salary which is 1 467 187.5
Common difference: 6
First term: 7
Second term: 13
Third term: 19
Fourth term: 25
Fifth term: 31
I hope this is correct and helps!
