The given series are:
3, 20, 63, 144, 275,?
We have to find, the value of missing term (?) =
Solution:
The pattern follow:
Previous number + 17, Previous number + 43(17 + 26), Previous number + 81(43 + 38), Previous number + 131(81 + 50, Previous number + 193(131 + 62), ......
20 = 3 + 17 = 20
63 = 20 + (17 + 26)
= 20 + 43 = 63
144 = 63 + (43 + 38)
= 63 + 81 = 144
275 = 144 + (81 + 50)
= 144 + 131 = 275
Similarly,
? = 275 + (131 + 62)
= 275 + 193 = 468
∴ Missing term (?) = 468
