Answer 1

Answer:

Answer is 63th term will be 132 more then 54th term

Answer 2

Answer:

first term i.e. a=3, d= 15 - 3 = 12

Let n i.e. an be the term which will be 132 more than its 54 term, then

Step-by-step explanation:

A.T.Q

an=132 + a54

a+(n-1)d = 132 + a+(54-1)d

3+(n-1)12 = 132 + 3+53×12

3+(n-1)12 = 132 + 639

3+(n-1)12 = 771

(n-1)12 = 771-3

n-1 = 768/3

n-1 = 258

n= 258+1 = 259
