Explanation:
Given:
6th term = 16 , n = 6
14th term = 32 ,n = 14
36th Term = ? , n = 36
Calculation :
6th term = 16 , n = 6
an = a + (n-1)d
16 = a + (6 - 1)d
16 = a + 5d .......... Eq 1
14th term = 32 , n = 14
32 = a + (14 -1)d
32 = a + 13d.............Eq 2
From, Equation 2 - 1
16 = 8d
16/8 = d
2 = d
value of (d) put in Eq 1
16 = a + 5x2
16 = a + 10
16 - 10 =a
6 = a
So , 36th Term = ? , n = 36
= a + (n -1)d
= 6 + (32-1)2
= 6 + (31)2
= 6 + 62
= 68
