What is the nth term of 4,9,16,25,36

(n + 1)²

Step-by-step explanation:

note that 4, 9, 16, 25, 36 are square numbers

To generate the terms add 1 to the position n and square, that is

first term : n = 1 → n = 1 + 1 → 2² = 4

second term : n = 2 → n = 2 + 1 → 3² = 9

third term : n = 3 → n = 3 + 1 → 4² = 16

Hence n th term is (n + 1)²

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
