Answer 1

Step-by-step explanation:

Given sequence => 3 , 15 , 27 , 39 , ...

Here t1 = a = 3

t2 = 15

d = t2 - t1 = 15 - 3 = 12

We know that

tn = a + ( n - 1 ) d

t54 + 132 = 3 + ( n - 1 )12

3 + ( 54 - 1 ) 12 + 132 = 3 + ( n - 1 ) 12

3 + 53 × 12 + 132 = 3 + 12n - 12

12n = 53 × 12 + 132 + 12

12n = 12 ( 53 + 11 + 1 )

n = 53 + 11 + 1

n = 65

The answer is 65 .
