Question

Find the 12th term of AP 3/4,5/4,7/4,9/4

Answer 1

Answer:25/4

Step-by-step explanation:

Use the formula An=A+(n-1)d

Where,

An is the nth term (here 12th term)

A is first term of an AP

n is total number of terms(here 12)

D is common difference between terms

Answer 2

Answer:

25/4

Step-by-step explanation:

solution

given,

A.P =$\frac{3}{4}$,$\frac{5}{4}$,$\frac{7}{4}$,$\frac{9}{4}$

NOW

FIND DIFFERENCE

d= 5/4-3/4 =2/4

a= 3/4

Now as we all know

t$t_{n}$=a + ( n-1) d

put all the values

$t_{12}$ =3/4 + ( 12-1) x 2/4

$t_{12}$=3/4 +11 x 2/4

$t_{12}$ =3/4 +22/4

$t_{12}$=3+22/4

$t_{12}$=25/4
