The general term of a sequence is given by an = 7+3 (n - 1) for n > 1. Which recursive formula defines this sequence?
A. An = 3an-1; a = 7
O
Ban =
10n-1; a1 = 1
C. An = an-1 + 3; aj = 0
D. An = an-1 + 3; aj = 4
E. Un = an-1 + 3; aj = 7

answer: the answer is 23

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

pi x^2

step-by-step explanation:

pi times x squared

answer: i believe it is c

step-by-step explanation:

because 5+4=9 so it would be 3^9
