Question

Find the missing term in the series that is 19,40,63,88,115,?,175,208

Answer 1

144 is the answer

19-40=21

40-63=23

63-88=25

88-115=27

115-144=29

144-175=31

175-208=33

Answer 2

Answer: The answer is 144.

Step-by-step explanation:  We are to find the missing term in the following series:

19, 40, 63, 88, 115, ? , 175, 208, . . .

We can see that the difference between two consecutive terms of the above sequences follows the following pattern:

$40-19=21,\\\\63-40=23,\\\\88-63=25,\\\\115-88=27,>~.~.~.$

Therefore, we will add (27 + 2 = 29) to 115 to get the missing term.

Thus, the missing term = 115+29 = 144.
