Question

the next two terms of the given sequence 1,3,7,15,31​

Answer 1

Answer:

63, 126

Explanation:

Formula to get answer: number x 2 + 1

1 x 2 + 1 = 3

1 x 2 + 1 = 33 x 2 + 1 = 7

1 x 2 + 1 = 33 x 2 + 1 = 77 x 2 + 1 = 15

1 x 2 + 1 = 33 x 2 + 1 = 77 x 2 + 1 = 1515 x 2 + 1 = 31

So, next two numbers will be:

31 x 2 + 1 = 63

63 x 2 + 1 = 126
