Starting with the numbers 1, build a sequence of 5 numbers

A number sequence. is a list of numbers arranged in a row. Let us look at two examples below. (i) 4, 6, 1, 10, 14, 5, … (ii) 4, 7, 10, 13, …. Number sequence (i) is a list of numbers without order or pattern. You cannot tell what number comes after 5. Number sequence (ii) has a pattern.

Step-by-step explanation:

Multiply the last number in the sequence (31) by 1 number higher (32). Then divide by 2. (31 * 32) / 2 = ?. Simplify to 31 * 16 = 496; Use the FOIL Method if you need a trick to multiply two digit numbers. Subtract 1 from 496 since the sequence started with 2. ANSWER is 495.

step-by-step explanation:

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
