Let us observe the given series 37,74,111,148

Here, the first term (a) = 37

Common difference(d) = 74-37 = 37

Hence, the given series is in Arithmetic progression.

Hence the nth term of the series is given by:

a_{n}=a+(n-1)d

Substituting the values of 'a' and 'd'.

a_{n}=37+37(n-1)

Therefore, it is the required explicit formula.

A₁ = 37
a₂ = 74
d = a₂ - a₁ = 74 - 37 = 37

a(n) = 37 + 37(n-1)

Find the surface area of the square pyramid below if the length of the sides of the base are 10 cm, and the slant height is 15 c
Damm [24]

The surface area of the square pyramid if the length of the sides of the base are 10 cm, and the slant height is 15 cm is 416.2 cm²

<h3>Surface area</h3>

Surface area of the square pyramid

= a² + 2a√a²/4 + h²

where,

  • a = sides of base = 10 cm
  • h = slant height = 15 cm

Surface area of the square pyramid

= a² + 2a√a²/4 + h²

= 10² + 2(10)√10²/4 + 15²

= 100 + 20√100/4 + 225

= 100 + 20√25 + 225

= 100 + 20√250

= 100 + 20(15.81)

= 100 + 316.2

= 416.2 cm²
