Question

,,,=,,=,,,,,=,, ,====4/,/4​

Answer 1

Answer:

$a = \frac{1}{2}$

$d = \frac{3}{2} - \frac{1}{2}$

$d = 1$

$an = a + ( n- 1)d$

$\frac{1}{2} + (n - 1)(1)$

$\frac{1}{2} + n - 1$

$n - \frac{1}{2}$

Answer 2

Explanation:

the first term is 1/2

the common difference =3/2 - 1/2=1

the n term =a+(n-1)d

nth term =1/2+(n-1)1

so

1/2+n-1=n term

after solving

(2n-2+1)/2=nth term

(2n-1)/2 is the nth term
