The next number in the sequence would be 30. The general rule is multiply by 2, then add 1. 1 x 2 = 2 2 + 1 = 3 3 x 2 = 6 6 + 1 = 7 7 x 2 = 14 14 + 1 = 15 15 x 2 = 30
The given sequence is an arithmetic progression. a = first term of A.P. = 10, d = common difference = an - an-1 = -4 nth term of an A.P. is given by: an = a+(n-1)d Plugging in the values we get an =...
To find out the equation for a sequence, the first thing you note is the difference between the numbers. In this case the difference is: -8, -8, -8, -8Thus the formula will be x-8n where x is not yet...
