Question

The sum of first 15 terms of an arithmetic sequences 450 what is its8 th term?​

Answer 1

Answer:

The 15 terms of the arithmetic sequence so obtained would be;

A - 7D, A - 6 D, A - 5 D, A - 4 D, A - 3 D, A -2 D, A - D, A, A+D, A+2 D, A +3 D, A+ 4 D, A +5 D, A+ 6D, and A +7 D.

Sum of the 15 terms of this arithmetic sequence = (A - 7 D) + (A - 6 D) + (A - 5 D) + (A - 4 D) + (A - 3D) + (A - 2 D) + (A - D) + (A) + (A +D) + (A + 2 D) + (A +3 D) + (A +4 D) +(A +5 D) +(A + 6 D) + ( A +7 D) = 15 A = 480 (given)

Therefore,

A = 480/15 = 32

So 8th term of the sequence = 32.
