Answer:31st term
Step-by-step explanation: Let n be the term for which is 55 more than the 20th term of an AP ...From Above
a=3 d=5 #a(nth) = 55+a(20th) a(20th) = a+19d = 98
Putting value in #a(nth) we get
a(nth)= 55+98=153
#General Formula of a term of AP, a(nth) = a+(n-1)d
Putting values in this formula,
153= 3+(n-1)5
n-1= 30
n=31
