Question

Which term of the AP: 3,15,27,39…... will be 132 more than its 54th term ?

Answer 1

Step-by-step explanation:

hi mate , here your answer !

a.p = 3,15,27,38...

a = 3

d = 15-3 = 12

n = 54

tn = a +(n-1)d

t54 = 3 + (54-1)12

= 3+(53)12

t54 = 639..

so, if t54 is 639 then 132 cannot be after 54th term ..
