Answer:
Given:
an=3+4n
To Find: d(common difference)
Solution:
The standard equation for for nth term of an A.P is:
⇒an=a+(n-1)d
From the given equation in question,
a1=3+4=7 [By Putting n=1]
∴a1=a=7 -----> 1
Now,
a2=3+8=11 [By Putting n=2 in given equation]
∴a2=11 -------->2
Also,
a2=a+(2-1)d [From the standard equation of A.P]
11=7+d [From 1 and 2]
∴d=4
Hope it helps you.
