Answer 1

22

Explanation:

t11 = a + 10d

= (-3) + 10(5/2)

= (-3) + 5(5)

= (-3) + 25

= 22

Answer 2

Answer:

For my pen☺

Explanation:

First term (a) = -3

Common difference (d) = Difference of two consecutive terms

= (-1/2) - (-3)

= (-1/2) + 3

= (-1 + 6 ) / 2

= 5/2.

Now,

=> nth term = a + (n − 1)d

=> 11th term = -3+ (11-1) (5/2)

=> 11th term -3 + 10 (5/2)

=> 11th term = -3 + 5 x 5

=> 11th term -3 + 25

.. 11th term = 22.
