Which of the following is equivalent to ? a. a0 + a1 + a2 + a3 + a4 + a5 b. a0 + a1 + a2 + . . c. a1 + a2 + a3 + . . + a∞ d. a1 + a2 + a3 + a4 + a5 . given the recursive formula shown, what are the first 4 terms of the sequence? a. 6, 25, 82, 253 b. 19, 45, 97, 298 c. 6, 19, 45, 97 d. 6, 11, 26, 71 which of the following is an arithmetic sequence with a common difference of 3? a. 1, 3, 9, 12, b. 17, 14, 11, 8, c. 4, 7, 10, 13, d. 12, 15, 19, 24, write a linear equation that represents the arithmetic sequence 10, 8, 6, 4, a. an = 10 + 2(n – 1) b. an = 2 + 10(n – 1) c. an = 10 + 2(n + 1) d. an = 10 – 2(n – 1)

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
