Step-by-step explanation:
In the recursive formula an = an−1 + 5

Suppose if a_5 is the nth term then previous term is a_4
To get the previous term we need to subtract 1 from the n
So a_n is the nth term
is the previous term
Here 5 represents the common difference between two terms
So value of previous term is represented by

Answer : 
Answer:
78 sqr units
Step-by-step explanation:
Use the Pythagorean Theorem to help find the base opposite the two.
The base of the second parallel line is sqrt( (15^2) - (12^2) ) = sqrt(81) = 9
The second base = 9 + 2 = 11
Area = (b1 + b2)*h/2
h = 12
b1 = 2
b2 = 11
h = 12
Area = (11 + 2)*12/2
Area = 13 * 12/2
Area = 78 square units
Answer:
B
Step-by-step explanation:
The equation is:
y = 2x + 3
Put x as 2.
y = 2(2) + 3
y = 4 + 3
y = 7
Put x as 3.
y = 2(3) + 3
y = 6 + 3
y = 9
Put x as 4.
y = 2(4) + 3
y = 8 + 3
y = 11
Put x as 5.
y = 2(5) + 3
y = 10 + 3
y = 13
