In a sequence of numbers, a, = 16, a. = 21, a. = 31 and a, = 36, based on this information, Which of the following equation that can be used to find the nth term in the sequence, an? an = 3n + 2
an = 5n + 1
an = 2n + 2
an = 5n + 3

Step-by-step explanation:

We are checking the sequences by calculating given terms from equations:

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.

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
