7.3 ------ 8.1 8.5 8.9

let us try to find the common difference here using last three terms

8.5-8.1=0.4

8.9-8.5=0.4

so it is clear that common difference is 0.4

so adding 0.4 to 7.3 will give the next term

7.3+0.4=7.7

Answer : missing number is 7.7

Answer:

Step-by-step explanation:

let base be b then height h = 2b + 4

The area (A) of a triangle is calculated as

A = $\frac{1}{2}$ bh ( b is the base and h the height ) , then

A = $\frac{1}{2}$ b(2b + 4) ← distribute parenthesis

A = b² + 2b

When b = 16 , then

A = 16² + 2(16) = 256 + 32 = 288 in²
