Consider the arithmetic sequence presented in the table below.

n 5 71
an 74 1,460

hint: an = a1 + d(n − 1), where a1 is the first term and d is the common difference.

part a: what is the first term, a1, of the sequence?

part b: what is the general term equation, an, for this sequence?

part c: what is the value of the 13th term of this sequence?

26) -2(7x) = (-2 • 7) x a. associative property of addition b. associative property of multiplication c. commutative property of multiplication d. commutative property of addition

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n − 1) + 4; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2; n > 1 i will award !
