In the given A.P.,
a = 3
d = 2
l = 201
We can find the last term of an A.P. by using the formula:
[tex] a_{n}= l-(n-1)d \\ a_{n} =201-(10-1)2 \\ a_{n}=201-18=183[/tex]
Hence, the 10th term from the end of the A.P. is 183.
a = 3

ali4249:
how can be the difference be 5
the difference is -2
It is not -2, it is 2, because d=a2-a1=5-3=2 (not -2).
why 5-2 we have to do the minus oflast second term with last
because it has been written that from last 10 th term
ok ok i got it
your formula is diff
we both have same ans
hmmm... YES..
He may have mistaken it...

Answer:
183.
Step-by-step explanation:
Given,
Arithmetic Progression = 3, 5, 7, 9,.... 201.
Now,
In the given Progression:
a = 3
d = 2
(where, d is the difference between two progressions.)
l = 201
We can find the last term of an A.P. by using the formula:
−(r−1)d
To Find,
10th term from that last of the progression will be:
= 201-(10-1)2
= 201-18
= 183
Hence, the 10th term from the end of the A.P. is 183.
