Question

Insert 4 arithmetic means between 4 and 324​

Answer 1

Answer:

it means

a=4,

6th term i.e., a+5d=  324

so d = (324-a)/5

    = 320/5 = 64

so a=4

a+d = 64+4 = 68

a+2d = 2*64+4 = 132

a+3d = 3*64+4 = 196

a+4d = 4*64+4 = 260

values are 68, 132, 196, 260

Step-by-step explanation:

Answer 2

Step-by-step explanation:

a=4, d=?, n=6 ,tn= 324

now tn = a+(n-1)d

324 = 4 + (6-1) d

324-4=5d

320 = 5d

d= 320/5 = 64

a1 = 4 +64

a2 = a1 +64 = 68+64 = 132

similarly

a3 = 196

a4= 260

hope it helps
