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

n

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

n = 1

.

\newline

a_n = 7n + 7

\newline

_____, _____, _____, _____

Find first term $a_1$ : $a_n = 7n + 7$ $\newline$ Find the first term of the sequence, $a_1$ . $\newline$ $a_n = 7n + 7$ $\newline$ $a_1 = 7(1) + 7$ $\newline$ $a_1 = 7 + 7$ $\newline$ $a_1 = 14$
Find second term $a_2$ : $a_n = 7n + 7$ $\newline$ Find the second term of the sequence, $a_2$ . $\newline$ $a_n = 7n + 7$ $\newline$ $a_2 = 7(2) + 7$ $\newline$ $a_2 = 14 + 7$ $\newline$ $a_2 = 21$
Find third term $a_3$ : $a_n = 7n + 7$ $\newline$ Find the third term of the sequence, $a_3$ . $\newline$ $a_n = 7n + 7$ $\newline$ $a_3 = 7(3) + 7$ $\newline$ $a_3 = 21 + 7$ $\newline$ $a_3 = 28$
Find fourth term $a_4$ : $a_n = 7n + 7$ $\newline$ Find the fourth term of the sequence, $a_4$ . $\newline$ $a_n = 7n + 7$ $\newline$ $a_4 = 7(4) + 7$ $\newline$ $a_4 = 28 + 7$ $\newline$ $a_4 = 35$
