Question

Complete the series
2,3,28,15,126,35,?

Answer 1

Answer:

344

Step-by-step explanation:

2,3,28,15,126,35

1³  + 1  = 2

2²  - 1  = 3

3³ + 1 = 28

4² - 1 = 15

5³ + 1 = 126

6² - 1 = 35

7³ + 1 = 344

8² - 1  = 63

There are two alternate series going  on

Tₙ = n³ + 1   for odd n

Tₙ = n² - 1    for n even

Answer 2

Answer:

Step-by-step explanation:

The pattern goes like  this friend

1^3  + 1  = 2

2^2  - 1  = 3

3^3 + 1 = 28

4^2 - 1 = 15

5^ + 1 = 126 ...........

KEEP ON DOING LIKE THIS AND THE ANSWER IS 344
