Decide whether the sequence is artithemetic, geometric or neither 2,6,10,16

We conclude that the sequence is NEITHER geometrc nor arithmetic.

Step-by-step explanation:

Given the sequence

As we know that

An arithmetic sequence has a constant difference d and is defined by:

Computing the differences between all adjacent terms:

The difference is not constant

Hence, the sequence is NOT arithmetic.

NOW, let's check whether is a geometric sequence or not

A geometric sequece has a constant common ration r and is defined by:

Computing the common ratios between all adjacent terms:

The ratio is not constant

Hence, the sequence is NOT geometric.

Therefore, we conclude that the sequence is NEITHER geometrc nor arithmetic.

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
