Question

Math ahh need done ASAP

Answer 1

• a=-2
• n=10

Now

• a_n=a+(n-1)d
• 25=-2+9d
• 9d=27
• d=3

Answer 2

• a) 3

Explanation:

Use the nth tern equation of the AP

• 
  `a_n=a_1+(n-1)d`

We have

• 
  `a_1=-2` and
  `a_(10)=25`

Find the value of d

• 25 = - 2 + (10 - 1)d
• 25 + 2 = 9d
• 27 = 9d
• d = 27/9
• d = 3

Correct choice is a)
