SSC CGL 20201)Select the letter-cluster that can replace the question mark (?) in the following series.
DJQC , ELTG , FNWK, GPZO ?
HRCS
D-> +1->E->+1->F->+1->G->+1=H ; J->+2->L->+2->N->+2->P->+2=R ; Q->+3->T->+3->W->+3->Z->+3=C ; C->+4->G->+4->K->+4->O->+4=S
SSC CGL 20202)Select the letter that can replace the question mark (?) in the following series.
Y , R, L, G, ?, Z
C
Y->-7->R->-6->L->-5->G->-4->C->-3->Z
SSC CGL 20203)Identify the number that does NOT belong to the following series.
2, 6, 14, 30, 62, 126, 250
250
(2 x 2) + 2 = 6, (6 x 2) + 2 = 14, (14 x 2) + 2 = 30, (30 x 2) + 2 = 62, (62 x 2) + 2 = 126, (126 x 2) + 2 = 254 (not 250)
SSC CGL 20204)Select the number that can replace the question mark (?) in the following series.
39, 50, 63, 80, ?, 122, 151, 182
99
The series follows pattern as,
39 + 11 = 50;
50 + 13 = 63;
63 + 17 = 80;
80 + 19 = 99;
99 + 23 = 122;
122+29 = 151;
151+31 = 182.
SSC CGL 20205)Select the letter will replace the question mark (?) in the following series.
A, J, E, L, I, N, O, P, U, ?
R
There are 2 series,
A, E, I , O , U And,J, L, N, P, ?;
2nd series follows pattern as,
J + 2 = L;
L + 2 = N;
N + 2 = P;
P + 2 = R;
SSC CGL 20206)Select the letter-cluster that can replace the question mark (?) in the following series.
NAVIGATE, PCVIGATE, NAXKGATE, ? , NAVIGAVG
NAVIICTE
The series follows pattern as,
NAVIGATE, PCVIGATE, NAXKGATE, ----TE, NAVIGAVG;
So, letter-cluster is NAVIICTE.
SSC CGL 20207)Select the letter-cluster that can replace the question mark (?) in the following series.
PROGRESS, QTOGRESS, QTRKRESS, ? , QTRKWKZA
QTRKWKSS
Here in every step of the series two consecutive letter of the first word is changed, like in first part, "PR" in PROGRESS is changed in a certain way like the alphabets are changed in a sequence of +1, +2, +3, +4, +5, +6, .... etc.
So, after, "QTRKRESS", R and E is replaced by R+5 = W and E+6 = K respectively to the missing word in the series is 'QTRKWKSS'.
SSC CGL 20208)Select the letter that can replace the question mark (?) in the following series.
C, E, H, J, M, 0, R, ?
T
SSC CGL 20209)Select the number that can replace the question mark (?) in the following series
45, 63, 101, 160, 241, ?
345
We can write series as,
4, 6, 10, 16, 24, ?
4 + 2 = 6;
6 + 4 = 10;
10 + 6 = 16;
16 + 8 = 24;
24 + 10 = 34;
So Next number is 345.
SSC CGL 202010)Select the letter that can replace the question mark (?) in the following series.
A, D, ?, P, Y
I
