Step-by-step explanation:
To Find :
- we have to find that 51 is a term of given AP or not.
Solution :
- Given AP :- 5, 8, 11 ,14 ....
As we know that,
where
- a = First term
- d = Common difference
- an = nth term
- n = number of terms
an = 51
d = a2 - a1
- a2 = 8
- a1 = 5
d = 8 - 5
d = 3
51 = 5 + (n - 1)3
51 - 5 = (n - 1)3
46 = (n - 1)3
46/3 = (n - 1)
46/3 + 1 = n
(46 + 3)/3 = n
49/3 = n
