Question

Determine the 10th term form the end of the ap 4,9,14,........254​

Answer 1

Step-by-step explanation:

Given A. P = 4,9,14.....254 .

First term = 4 .

Common difference = 5 .

Finding, 254 is which Term of the A. P from the beginning .

254 = 4+(n-1)5

250 =( n-1 )5

50 = n-1

n = 51 .

Hence, 254 is the 51 th term of the A. P.

From 254 or end of A. P the tenth term would be 42 term of A. P.

42 th term of A. P = 4 + 41(5)= 4+205 =209 .
