 Hello and welcome to the session. In this session we will discuss a question which says that using the given explicit formula for the arithmetic sequence, find the eighth and eleventh term of the sequence and the given explicit formula is, the n is equal to minus 17n plus 24. Now let us start with the solution of the given question. In this question we are given the explicit formula for the arithmetic sequence and we will find the eighth and eleventh term of the sequence using this formula. So we are given a n is equal to minus 17n plus 24. First of all let us find eighth term of the sequence for this we will put n is equal to 8 in the given formula. So we have a 8 is equal to minus 17 into 8 plus 24 which is equal to, now minus 17 into 8 is minus 136 plus 24 that is equal to minus 112 thus the sequence is minus 112. Now let us find eleventh term of the sequence which we will put n is equal to 11 in the given formula and we have a 11 is equal to minus 17 into 11 plus 24 which implies a 11 is equal to, now minus 17 into 11 is minus 187 plus 24 which implies a 11 is equal to minus 163 thus eleventh term of the sequence is minus 163 which is minus 112 and eleventh term of the sequence is minus 163 and this is the required answer. So this completes the session and if you have enjoyed this session.
