Answered by paryuljain23

The middle term = the average of the first term and the last term.

For example, the arithmetic sequence

1, 4, 7, 10, 13, 16, 19

which has 7 terms (7 is an odd number of term)

sshazu5856: actually the middle term is for examlpe if there is atotal of 29 terms ...so u add 1 to 29 and divide it by 2 u will get the midle term...ie,30 /2=15 therefore the midlle most term of the 29 terms is 15th term

sshazu5856: this is actually easy and note tht the total no. of terms for such questions is always odd no. so as i said just add 1 and divide the whole no. by

sshazu5856: divide the whole no. by

sshazu5856: divide the whole no. by 2
