a_(n)=7n-1 9 ( what is the fourth term) PLEASE HELP ASAP. July 31, 2021 by Hải Đăng a_(n)=7n-1 9 ( what is the fourth term) PLEASE HELP ASAP.

Answer: Fourth term of given arithmetic progression a(4) = 30 Step-by-step explanation: Given incomplete information: a(n) = 7n – 1 9 Assume Correct information: a(n) = 7(n – 1) + 9 Find: Fourth term of given arithmetic progression Computation: Fourth term of given arithmetic progression = a(4) So, Number of term (n) = 4 So, a(n) = 7(n – 1) + 9 a(4) = 7(4 – 1) + 9 a(4) = 7(3) + 9 a(4) = 21 + 9 a(4) = 30 Fourth term of given arithmetic progression a(4) = 30 Reply

Answer:Fourth term of given arithmetic progression a(4) = 30

Step-by-step explanation:Given incomplete information:

a(n) = 7n – 1 9

Assume Correct information:

a(n) = 7(n – 1) + 9

Find:

Fourth term of given arithmetic progression

Computation:Fourth term of given arithmetic progression = a(4)

So,

Number of term (n) = 4

So,

a(n) = 7(n – 1) + 9

a(4) = 7(4 – 1) + 9

a(4) = 7(3) + 9

a(4) = 21 + 9

a(4) = 30

Fourth term of given arithmetic progression a(4) = 30
