Question

5. Find the 11 term from the last term (towards the first term) of the AP: 10.7, 4, ..,

-62​

Answer 1

Step-by-step explanation:

Given: AP: 10.7, 4, ..,-62

n=11

To find: A11=?

Reverse the AP. i.e.i,

-62.......4, 7, 10.

Now, a=-62,. d=10-7=3.

$an = a + (n - 1) \times d$

A11=-62+(11-1)×3

=>-62+10×3

=>-62+30

=>-32.

The 11 term from the last term is -32.

Answer 2

Answer:

-26

Step-by-step explanation:

a = l = -62

d = - (7 - 10) = 3

n = 11

an = a + (n - 1)d

an = -62 + (11 - 1) 3

an = -62 + 30

an = -32
