1, 3, 6, 10, 15 is it arithmetic, geometric or neither
Gekata [30.6K]

The given sequence is neither arithmetic nor geometric.

Further explanation:

In order to check whether a sequence is geometric or arithmetic we have to find the common ratio and common difference respectively

Common difference is the deifference between cunsecutive terms of a sequence while common ratio is the ratio between two consecutive terms.

Common difference is denoted by d and common ratio is denoted by r

  • If the common difference is same then the given sequence is an arithmetic sequence
  • If the common ratio is same then the given sequence is a geometric sequence

Given

1, 3, 6, 10, 15

Common difference:

Here

a_1=1\\a_2=3\\a_3=6\\a_4=10\\a_5=15\\Common\ Difference=a_2-a_1=3-1=2\\a_3-a_2=6-3=3\\a_4-a_3=10-6=4

As the common difference is not same, the given sequence is not an arithmetic sequence

Common Ratio:

r=\frac{a_2}{a_1}=\frac{3}{1}=3\\\frac{a_3}{a_2}=\frac{6}{3}=2\\\frac{a_4}{a_3}=\frac{10}{6}=1.6

As the common ratio is also not same the sequence is not a geometric sequence.

The given sequence is neither arithmetic nor geometric.

On a coordinate plane, Broadway is 4 units to the right and 4 units up. Empire State Building is 1.50 units to the right and 1 u
wariber [46]

Answer: (1.5, 1.0)

Step-by-step explanation:

On coordinate plane , if we plot a point , we start from origin that is (0,0).

Direction for Empire State Building :  1.50 units to the right and 1 unit up to the origin .

By considering origin as the initial point, frim we move 1.45 units to the right on x-axis( positive) showed by red

Then move 1 unit up parallel to positive y axis showed by green.

So, the ordered pairs show the location of the Empire State Building = (1.5, 1.0)   [as both axis are positive in this region.]

So correct option = (1.5, 1.0)
