Calculate the explicit formula
Calculate term number 10
And the Sum of the first 10 terms for:
638,698,758
Explicit Formula
an = a1 + (n - 1)d
Define d
d = Δ between consecutive terms
d = an - an - 1
We see a common difference = 60
We have a1 = 638
an = 638 + 60(n - 1)
Calculate Term (4)
Plug in n = 4 and d = 60
a4 = 638 + 60(4 - 1)
a4 = 638 + 60(4 - 1)
a4 = 638 + 60(3)
a4 = 638 + 180
a4 = 818
Calculate Term (5)
Plug in n = 5 and d = 60
a5 = 638 + 60(5 - 1)
a5 = 638 + 60(5 - 1)
a5 = 638 + 60(4)
a5 = 638 + 240
a5 = 878
Calculate Term (6)
Plug in n = 6 and d = 60
a6 = 638 + 60(6 - 1)
a6 = 638 + 60(6 - 1)
a6 = 638 + 60(5)
a6 = 638 + 300
a6 = 938
Calculate Term (7)
Plug in n = 7 and d = 60
a7 = 638 + 60(7 - 1)
a7 = 638 + 60(7 - 1)
a7 = 638 + 60(6)
a7 = 638 + 360
a7 = 998
Calculate Term (8)
Plug in n = 8 and d = 60
a8 = 638 + 60(8 - 1)
a8 = 638 + 60(8 - 1)
a8 = 638 + 60(7)
a8 = 638 + 420
a8 = 1058
Calculate Term (9)
Plug in n = 9 and d = 60
a9 = 638 + 60(9 - 1)
a9 = 638 + 60(9 - 1)
a9 = 638 + 60(8)
a9 = 638 + 480
a9 = 1118
Calculate Term (10)
Plug in n = 10 and d = 60
a10 = 638 + 60(10 - 1)
a10 = 638 + 60(10 - 1)
a10 = 638 + 60(9)
a10 = 638 + 540
a10 = 1178
Calculate Sn:
Sn = Sum of the first n terms
Sn = | n(a1 + an) |
2 |
Substituting n = 10, we get:
S10 = | 10(a1 + a10) |
2 |
S10 = | 10(638 + 1178) |
2 |
S10 = | 10(1816) |
2 |
S10 = | 18160 |
