Q. Find the first three terms of the sequence defined below, where nn represents the position of a term in the sequence. Start with n=1n = 1.\newlinean=7na_n = 7n\newline___, ___, ____
  1. Find first term a1a_1: an=7na_n = 7n\newlineFind the first term of the sequence, a1a_1.\newlinean=7na_n = 7n\newlinea1=7(1)a_1 = 7(1)\newlinea1=7a_1 = 7
  2. Find second term a2a_2: an=7na_n = 7n\newlineFind the second term of the sequence, a2a_2.\newlinean=7na_n = 7n\newlinea2=7(2)a_2 = 7(2)\newlinea2=14a_2 = 14
  3. Find third term a3a_3: an=7na_n = 7n\newlineFind the third term of the sequence, a3a_3.\newlinean=7na_n = 7n\newlinea3=7(3)a_3 = 7(3)\newlinea3=21a_3 = 21
