Question

in an arthemetic progression a=5,a4=9 1/2,find a2 and a3​

Answer 1

Step-by-step explanation:

given common difference of an a.p series is 5 and 4th term of it is 9 1/2 = 19/2

we know a(n+1)th term - a(n)th term = common difference

so a4-a3=5

so a3=a4-5=19/2 -5 = 9/2

similarly

a3-a2=5

so a2=a3-5

so a2= 9/2-5=-1/2

so a2=-1/2 and a3= 9/2

hope you understood goodluck buddy:)
