Question

Q 23. Find the missing term in the series given below. -1, 0, 5, 14, ?, 44​

Answer 1

Answer:

27

Step-by-step explanation:

-1 = 2((-1)^2) + 3(-1)

0 = 2(0^2) + 3(0)

5 = 2(1^2) + 3(1)

14 = 8 + 6 = 2(2^2) + 3(2)

44 = 32 + 12 =2(4^2) + 3(4)

So, the pattern is 2(n^2) + 3n where n = -1,0,1,2,3,4

Hence, the missing number is 2(3^2) + 3(3) = 18 + 9 =27
