Answer:Hey brother here is your answer.
Step-by-step explanation:
Given 2nd term is 6.
So, by A.P. formula, a+(n-1)d=term.
Putting the values,
a+(2-1)d=6
Therefore a+d=6 ----(1)
Also, a+(5-1)d=48
Therefore a+4d=48 ----(2)
Subtracting (1) by (2), we get
3d=42, d=14
Now using the value of d in (1) we get
a=(-8).
The A.P. becomes -8, 6, 20, 34......
Now we have to find the 10th term,
here, a=-8
d=14
n=10
Using values,
-8+(10-1)×14 ==> -8+9×14 ==> -8+126 ==> 118.
Therefore the 10th term of this A.P. is 118.
