Question

Find the 17th term from the end of the AP: 1,6,11,16....201,216

Answer 1

hmmm...

first term =1

common difference=6-1=5

now,

tn=a+(n-1) d

216 =1+(n-1) 5

215/5=n-1

n=44

hence 44 terms in this series

so, from last 17th term=from first (44-17+1) th term = 28th term from first

now,

28th term=a+(28-1) d

=1+27 x 5 =136
