Question

Write the first three terms of the A.P. whose first term is -7 & common difference is 1/2.​

Answer 1

Answer:

Solution:- -7,-13/2,-6,...........

is the required A.P.

Step-by-step explanation:

Solution:- Here

a= t1= -7

and d=1/2

therefore for any A.P.

tn=a+(n-1)d

t2= -7+(2-1)1/2

t2= -7+1/2

t2=-13/2

and ,

t3=-7+(3-1)1/2

= -7+1

= -6

t3= -6
