- 2. Multiple ChoiceA list of numbers -10, -6, -2, 2 is _________an A.P with d = -16an A.P with d = 4an A.P with d = -4Not an A.P
- 3. Multiple ChoiceThe first four terms of an Arithmetic Progression whose first term is -2 and the common difference is -2 is _____-2, 0, 2, 4-2, 4, -8, 16-2, -4, -6, -8-2, -4, -9, -16
- 4. Multiple ChoiceWhich of the following is not an Arithmetic Progression?1, 4, 7, 10, .....-5, -2, 1, 4, .....3, 7, 12, 16, ......11, 14, 17, 20, .....
- 5. Multiple ChoiceS
_{n}= a +......+ T_{n}

S_{n}= T_{n}_{}+ ....+ a

how do you calculate S_{n}n(a + T_{n})n/2(a + T_{n}) - 6. Multiple ChoiceS
_{n}= a +......+ T_{n}

when you substitute T_{n}with its formula, S_{n}will be...n[(a + (n-1)d]n/2[2a + (n-1)d ] - 7. Multiple ChoiceHow many terms of the arithmetic series 18 + 15 + 12 +...have to be taken so that it sum is zero.

Which formula can be usedTnSn = n/2 [a + Tn]Sn = n/2 [2a + (n-1)d] - 8. Multiple ChoiceFind the first term of the given sequence:

a_{14}=68

d=314202629 - 9. Multiple ChoiceGiven the sequence:

25, 21, 17, 13,...

Write the explicit equation that models the sequence.a_{n}= 4n + 29a_{n}= -4n + 25a_{n }= -4n + 29a_{n}= 4n + 25 - 10. Multiple ChoiceCreate the explicit formula for the sequence:

2, 8, 14, ...a_{n}=2+6na_{n}=-6+6na_{n}=6n-4a_{n}=4-6n - 11. Multiple ChoiceThe next two terms of the sequence

4, 7, 10, 13 are ....16 and 1915 and 1916 and 1815 and 18 - 12. Multiple ChoiceChoose the correct answer from the given four options:

In an AP, if d = –4, n = 7, a_{n}= 4, then a is672028 - 13. Multiple ChoiceChoose the correct answer from the given four options:

In an AP, if a = 3.5, d = 0, n =101 ,then a_{n}will be03.5-3.51 - 14. Multiple ChoiceChoose the correct answer from the given four options:

The 21st term of the AP whose first two terms are –3 and 4 is17137-137127 - 15. Multiple ChoiceIf the 2nd term of an AP is 13 and the 5th term is 25, the common difference is12435
