Question

find the 10th term from the end of the ap -5,-10,-15.....-1000​

Answer 1

Answer:

=> -950

Step by step explanation:

a = -5

d = -5

l = -1000

So, first of all we need to find No. of terms in the A.P.(n)

l = a+(n-1)d

-1000 = -5+(n-1)*-5

-1000 + 5 = (n-1)*-5

-995 = (n-1)*-5

-995/-5 = (n-1)

199 = n-1

n = 200

Now,

10th term from end will be 190.

So,

a190= a + 189d

= -5 + (189*-5)

= -5 + (-945)

= -5 -945

= -950
