Question

Find the first term and common difference for the A.P.:−5,−8,−11​

Answer 1

Step-by-step explanation:

Given in A.P. First term (a)= -5

And common difference (d)= second term -first term

So,d= -8-5

= -13

Answer 2

Answer:

First term = -5

Common difference = -3

Step-by-step explanation:

First term = -5

Second term = -8

Third term = -11

Common difference = Second term - First term

= -8 -(-5)

= -8+5

= -3
