Find the last term of an arithmetic sequence whose a=5,d=3 and n=78

_________

Un = a + (n - 1) × b

U78 = 5 + (78 - 1) × 3

U78 = 5 + 77 × 3

U78 = 5 + 231

U78 = 236

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.

step-by-step explanation:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
