Answer:
10th Term = 33
Step-by-step explanation:
3rd Term = a + 2d = 12
7th Term = a + 6d = 24
Eq. 1 : a + 2d = 12
a = 12 - 2d
Eq. 2 : a + 6d = 24
Putting the value of a in Eq. 2
( 12 - 2d ) + 6d = 24
12 + 4d = 24
4d = 24 - 12
d = 12/4
d = 3
Since,
a = 12 - 2d
= 12 - 2(3)
= 12 - 6
= 6
a = 6
Now,
10th Term = a + 9d
= 6 + 9(3)
= 6 +27
= 33
