Question

The 10th term of AP is -4 and its 22nd term is -16. Its 38th term is *


​

Answer 1

Answer:

-32

Step-by-step explanation:

a+9d=-4

a+21d=-16

by substituting

-4+(-9d)=-16+(-21d)

-4+16=9d+(-21d)

12=-12d

-1=d

by putting d in a+9d=-4

a+-9(-1)=-4

a=9-4

so, a=5

= a +(38-1)d

= 5 + 37(-1)

= 5 + (-37)

= -32
