Question

1. the function ( a(n) = 4n + 3 ) represents the value of the ( n )th term in a sequence. what is the sum of the 1st and 7th terms in the sequence?

type a response

Explanation:

Step1: Find the 1st term

To find the 1st term, substitute \( n = 1 \) into the function \( a(n)=4n + 3 \).
\( a(1)=4(1)+3=4 + 3 = 7 \)

Step2: Find the 7th term

To find the 7th term, substitute \( n = 7 \) into the function \( a(n)=4n + 3 \).
\( a(7)=4(7)+3=28 + 3 = 31 \)

Step3: Find the sum of the 1st and 7th terms

Add the 1st term (\( 7 \)) and the 7th term (\( 31 \)).
\( 7+31 = 38 \)

Answer:

38
