Hi Mate!!!
t5 = a + 4d
where d is common difference and a is ist term
a + 4d = 12
4d = 12 - a
4d = 10
d = 5 / 2
t2 = a + d t3 = a + 2d
t5 = a + 4d
where d is common difference and a is ist term
a + 4d = 12
4d = 12 - a
4d = 10
d = 5 / 2
t2 = a + d t3 = a + 2d

t5=12
a+4d=12
2+4d=12
4d=12-2
4d=10
d=10/4
d=2.5
Now,
t2=a+d
=2+2.5
=4.5
t3=a+2d
=2+2×2.5
=2+5
=7
t5=a+4d
=2+4×2.5
=2+10
=12.
a+4d=12
2+4d=12
4d=12-2
4d=10
d=10/4
d=2.5
Now,
t2=a+d
=2+2.5
=4.5
t3=a+2d
=2+2×2.5
=2+5
=7
t5=a+4d
=2+4×2.5
=2+10
=12.
