+1348 The sequence 24, $a$, $b$, $c$, $d$ 60 is arithmetic. What is the value of $a+b+c+d$?
+290 60 - 24 = 36, so we can divide 36 by 5 because we have to add a number 5 times, and we get 7.2, so the arithmetic sequance is growing by 7.2 each progressive term.
24, 24 + 7.2, 24 + 14.4, 24 + 21.6, 24 + 28.8, 60
a = 31.2
b = 38.4
c = 45.6
d = 52.8
a + b + c + d = 168
Answer: 168
