No, it would be 62. The equation is: f(n) = 2(f(n - 1) + 1), with f(0) = 0. So f(5) = 2(30 + 1) = 62
Usually the letter n stands for number, and it means some unspecified number.
decreased
n+m
x+5: - means a number increased by 5 n - 3: - means a number decreased by 3 5x: - means 5 times a number 5n + 3: - means 3 more than 5 times a number 100 - means one hundred divided by a number n
n+6.2
n+19
8+n
Call the number we are looking for n. Increased by 2/3 means 2/3n and we are told the 2/3n +n=35 So (5/3)n=35 or 5n=105 so n=21 so let's check 2/3 of 21 is 14 and 14 + 21 = 35.
It is -29+N.
If ten times the number n decreased by 13 is equal to the square of the same number n increased by 3, then the value of n is either 8 or 2.
n + 2
n+5
Suppose the number is N.Then (N + 4)*2 = N + 20that is, 2N + 8 = N + 20subtracting N from both sides gives: N + 8 = 20subtracting 8 from both sides gives: N = 12.
