Let see how to build up this formula that is going to give that term of rank n
1st term =a₁ & r is the ratio
1st a₁ = a₁ x r°
2nd a₂ = a₁ x r¹
3rd a₃ = a₁ x r²
4th a₄ = a₁ x r³
5th a₅ = a₁ x r⁴
.......................
.......................
nth : a(n) = a₁ x r⁽ⁿ-¹)
Note when that the subscript of a is the same as the exponent mines 1
32 + 20
GCF = 4
32/4 = 8
20/4 = 5
(4 * 8) + (4 * 5) =
4(8 + 5) <==
