Q. Find the first five terms of the sequence defined below, where

n

represents the position of a term in the sequence. Start with

n = 1

.

\newline

a_n = 8n − 6

\newline

_____, _____, _____, _____, _____

Find first term: Find the first term of the sequence, $a_1$ . $\newline$ $a_1 = 8n − 6$ $\newline$ Substitute $n = 1$ into the formula to find $a_1$ . $\newline$ $a_1 = 8(1) − 6$ $\newline$ $a_1 = 8 − 6$ $\newline$ $a_1 = 2$
Find second term: Find the second term of the sequence, $a_2$ . $\newline$ $a_2 = 8n - 6$ $\newline$ Substitute $n = 2$ into the formula to find $a_2$ . $\newline$ $a_2 = 8(2) - 6$ $\newline$ $a_2 = 16 - 6$ $\newline$ $a_2 = 10$
Find third term: Find the third term of the sequence, $a_3$ . $\newline$ $a_3 = 8n − 6$ $\newline$ Substitute $n = 3$ into the formula to find $a_3$ . $\newline$ $a_3 = 8(3) − 6$ $\newline$ $a_3 = 24 − 6$ $\newline$ $a_3 = 18$
Find fourth term: Find the fourth term of the sequence, $a_4$ . $\newline$ $a_4 = 8n - 6$ $\newline$ Substitute $n = 4$ into the formula to find $a_4$ . $\newline$ $a_4 = 8(4) - 6$ $\newline$ $a_4 = 32 - 6$ $\newline$ $a_4 = 26$
Find fifth term: Find the fifth term of the sequence, $a_5$ . $\newline$ $a_5 = 8n - 6$ $\newline$ Substitute $n = 5$ into the formula to find $a_5$ . $\newline$ $a_5 = 8(5) - 6$ $\newline$ $a_5 = 40 - 6$ $\newline$ $a_5 = 34$
