g Let an denote the number of subsets of {1, 2, . . . , n} with no consecutive terms. Find a recurrence relation for an together with an appropriate number of initial terms

28

step-by-step explanation:

because that's the answer

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

2/3=10/15

1/5=3/15

10+3=13/15

2 13/15 is the answer
