    Let V be first term and be the common difference then,
                     a = 7
                   straight d equals 21 over 2 minus 7
                    space space space space space equals fraction numerator 21 minus 14 over denominator 2 end fraction equals 7 over 2
    We know that, an = a + (n -1)d      space space space space space space space space space space space open square brackets because space open parentheses straight a subscript straight n equals 1 close parentheses close square brackets
