Plz ! its due now. will mark ! express the terms of the following sequence by giving an explicit formula. 7/2 , 7 , 21/2 , 14 , . . a. u(n) = 7/2 + 7/2n, where n = 0, 1, 2, 3, . . b. u(n) = 7/2 + n, where n = 0, 1, 2, 3, . . c. u(n) = 7/2n + 7/2n, where n = 0, 1, 2, 3, . . d. u(n) = 7/2n, where n = 0, 1, 2, 3, . .

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

thus, the first answer choice, y = sec x, is the correct one
