Arithmetic 81808

An increasing arithmetic sequence has an odd number of terms. The middle term is 302. If we remove the 4 largest terms from the sequence, the middle term will be 296. Determine the difference in the sequence.

Correct answer:

d =  3

Step-by-step explanation:

d>0 a + d (n+1)/2=302 a + d (n4+1)/2=296  n=4+4+1=9  a+d (n+1)/2=302 a+d (n4+1)/2=296 a+d (9+1)/2=302 a+d (94+1)/2=296  2a+10d=604 2a+6d=592  Row2Row1Row2 2a+10d=604 4d=12  d=412=3 a=260410d=260410 3=287  a=287 d=3
