Question

An AP consists of 60 terms. If the first and last terms are 6 and 124 respectively, find the 27th term.​

Answer 1

Step-by-step explanation:

n=60, an=124, a=6

Now, an=a+(n-1)d

124=6+(60-1)d

59d=124-6

d=118/59

d=2

For 27th term:-

a27=a+26d

=6+26×2

=58

Therefore, 58 is the 27th term of the given A.P
