What is the value of x2, x3, x4, x5…of the terms (of arithmetic progression) when x1 = 8 and x6 = 20?

Correct answer:

x2 =  10.4
x3 =  12.8
x4 =  15.2
x5 =  17.6

Step-by-step explanation:

x1=8 x6=20  xn = x1 + d (n1) x6 = x1+5d d=5x6x1=5208=512=252=2.4  x2=x1+d=8+512=58 5+512=540+512=540+12=552=1052=10.4
x3=x2+d=552+512=552+12=564=12.8
x4=x3+d=564+512=564+12=576=15.2
x5=x4+d=576+512=576+12=588=17.6
