Answer 1

Answer:

first u write the whole question because there can be no question like this every question is given like , given Ap 5 ,2 ,3 .... 67 find the 10th term

Answer 2

$a = 5$

$n = 10$

$\binom{a}{ \: \: \: \:10} = 67$

$\binom{a}{ \: \: \: n } \: = a \: + \: (n - 1)d$

$\binom{a}{ \: \: \: \: \: \:10} \: = 5 + (10 - 1)d$

$67 = 5 + 9d$

$9d = 67 - 5$

$d = \frac{62}{9}$
