Step-by-step explanation:
Given: 10th=23 and 32nd=67 term of an AP.
an= a+(n-1)d
a10=a+(10-1)d=23
a10=a+9d=23———eq-1
a32=a+(32-1)d=67
a32=a+31d=67———eq-2
Now subtract eq1-eq2
-22d=-44
d=-44/-22
d=2
Now put the value of (d) in eq1
a+9(2)=23
a=23-18
a=5
So Common difference =2
First term =5
Hope this will help you!
