Question

find the first term and common difference for each of A.P. 127,135,143,151​

Answer 1

Answer:

first term = 127

common difference = 8

Step-by-step explanation:

common difference =   135 - 127 =8

                                      143 - 135 = 8

                                      151 - 143 = 8

Answer 2

a=127,d=8

Step-by-step explanation:

let the first term be 'a'and the common difference be 'd'.

We know that t1=a

therefore a=127

d=t2-t1

=135-127

=8

that is d=8
