Question

in an ap if d=-1,an=36 ,n=14 then a is​

Answer 1

Answer:

given, an=36, n=14, d=-1 a=?

Step-by-step explanation:

an=a+(n-1)d

36=a+(14-1)(-1)

36=a+(-13)

36=a-13

36+13=a

49=a

Answer 2

Question :-

• in an ap if d=-1,an=36 ,n=14 then a is?

Solution :-

Given:

$d = - 1, \: \: \: a_n = 36 , \: \: \: n = 14$

What to find out = a (first term)?

We know that,

$a_n = a + (n - 1) \times d$

So,

$36 = a + (14 - 1) \times ( - 1)$

$36 = a - 13 = > a = 49 \: \: \: \: ans$
