Remember taht 5 over 4 is 1.25, that is equivalent so A and B are equal, now to convert 12.5% we just need to divide that by 100, that would be .125 so that is not actually 1.25, so that is not equal, the last one is 125% divided by 100 is 1.25, so the only one that is not equal or equivalent to the others would be C:12.5%.
First you see how it goes up 6 each time this is the start of your nth term rule 6n Then -6 from the first term to get the ‘0th term’ 1-6=-5 So nth term rule is 6n-5 hope this helps
A for the first because there are 4 aces and 1 nine of hearts. that makes it 5 cards of the 52 in a deck d for the second because there are two cards: the queen of heart and and ace of diamond out of the 52
